good evening. thank you for joining us. it's been called a new tomorrow of sexual assault. online extortion.

what's driving this growing threat, tonight we hear from the victims, young, vulnerable, and exposed. here's abc's lindsey davis. >> reporter: with the click of a mouse the beauty queen's moment to shine turned into her darkest days. >> i was happenway through my reign has miss california when i found out i had a stalker. >> reporter: class di wolf, 2013's miss teen usa said it was someone with an arsenal of private, personal images of her. >> i got an anonymous e-mail from someone and basically it was stating three things, if i didn't do what he said, he was doing to release all the photos that he had of them. >> reporter: she was a victim of an online crime that is a growing concern. it's called sextortion. in wolf's case, she says she was shocked to learn the pictures

even existed. >> i had no idea what he was talking about because i'd never taken photos before. >> reporter: it pushes out a hacker took over the web cam on her computer and secretly recorded her for a year, watching her get ready for school in the morning and undress at night. >> he gave me three options. the first was to send him better quality photos. the second option was to snap chat him, and the third option was to skype him for five minutes and do what he said. if i didn't, he would blackmail me. he did it. i would receive 30 e-mails a day of him harassing me, asking for me. >> reporter: her online manipulation lasted for several months until finally her cyber peeping tom turned himself into the fbi and was sentenced to 1 months in prison, and the biggest surprise for wolf, it was someone she knew. >> the whole entire time i was

receiving e-mails from this guy, i pictured a creepy guy in a basement halfway across the world, but then i found out it was someone i went to high school with that lived in my hometown. >> reporter: but in many cases, the back mailer is anonymous. as students at george mason university discovered that this week. >> to hear there were two more cases was disturbing. >> reporter: an e-mail from university officials sounded the alarm that unknown suspects gained the trust of two students over the internet enticing them to broadcast sexual acts over their web cams. once they said, the suspects recorded the video and threatened to post them on the internet if they didn't pay $5,000. >> this is calculated, it's cold hearted, and malicious sadism. >> reporter: it's something the department of justice says is becoming common, especially when it comes to children. the vast majority of the victims

are female and minors. >> reporter: why do the victims fall for this? >> victims are in their young teens. they're experimenting. suddenly there's this person who is giving you all this wonderful validation. and that's the perfect storm for an offender to take advantage. >> reporter: in one particularly heinous case, a 26-year-old man named lucas michael chancellor terrorized more than 350 young girls on social media and chat sites. >> none of us in jacksonville, including the task force officers and fellow agents working these types of violations for years, we've never seen anything like this before. >> reporter: chancellor entered online chat rooms popular with girls going by numerous online names. he posed as a teenage boy interested in skateboarding. he asked his prey to video chat and then strip and perform a series of specific poses all the

while secretly recording them. one of the targets says she felt like his captor. >> as i'm doing this, he would be like no, this isn't right. this one is blurry or you didn't do this right. you weren't doing it right. you got to do it again. and that's where bag slave to him comes in, because i had to make sure i come plied. >> reporter: he amassed more than 80,000 images and videos that he used to threaten the girls saying he would hurt them or their families if they didn't give him more. he labeled his files marking them done when he was satisfied with his blackmailing. >> next to the victim's name he'd have notes to himself like i remember one was will try again. another was a note on facebook now. samantha was 13 years old when she and a friend encounters him online. >> he was in a chat room when we were chatting with people we thought were our age.

asked us to flash our breasts, and he snapped a picture. >> reporter: he resurfaced, ready to manipulate her. >> i was afraid and scared, and as a 13-year-old, you really -- you believe that someone is going to do those things they said they're going to do to you. >> reporter: she says over the course of the next several hours chancellor directed her through his poses asking her to perform graphic sex acts she'd never heard of. finally he seemed satisfied and left samantha alone. she says she immediately deleted her social media accounts and never told anyone about the encounter. >> i was afraid every day he would come back and taunt me. >> reporter: chancellor told the fbi he sought out girls in their early teens specifically. >> he said because older girls wouldn't fall for his ploy. >> reporter: he used multiple servers that hid his identity, routing his communications through other countries. that's how some of them get away with it according to an

attorney. >> local law enforcers don't know what to do. they don't want to prosecute or worry about offenders on the other side of the world which happens with these types of internet crimes. >> reporter: chancellor was prosecuted in 2014 and sentenced to 105 years in federal prison. only about a third of his victims have been identified. they're encouraging more to come forward. samantha says she's glad to see him put away. >> it was overwhelming but it felt good to confront the guy who caused me so much pain and suffering. >> reporter: she said the experience has left her changed forever. >> i became suicidel. i've attempted suicide. and i live with anxiety now. i can't walk down the street and feel comfortable if i get looked

at by a strange man. >> reporter: how concerned are you about sextortion. >> i think there couldn't be anything more important for our country to be focusing on as a new crime that needs to be really, really, really concentrated upon. >> what is sextortion. >> reporter: the fbi put this video on their website counseling teens on how to protect themselves. because they're not alone, samantha says other girls shouldn't feel embarrassed if they fall for a scam. >> the best thing you can do is to reach out to someone who cares about you and you can trust and seek help. >> reporter: for "nightline," i'm lindsey davis in new york. up next, fashion sfliflirti with important. just how far is too far? plus, when silence is golden, a gaffe is the latest in

. >> fashion giant calvin klein is no stranger to controversy. ads pushing limits for decades, but tonight pushback against what some are calling fashion porn. she's lindsey janice. >> reporter: if you think you've seen it all from calvin klein, think again. this is their latest underwear campaign. this photo showing 23-year-old model flashing the camera with a provocative shot looking up her skirt.

with the caption, i flash in my calvins. along with the hash tag, take a peek. >> people called it perverted. pretty negative. >> reporter: the rest don't leave much to the imagination either. highly sexualized and suggestive images. kendall jenner squeezing a grapefruit. a molds wearing her jeans backwards with the word belfie. another with her hands inside her underwear. the ads immediately coming under fire. thousands of comments on social media. specifically blasting that up thekirt shot. saying it looks more like porn than fashion. calling it disgusting and unnecessary. >> they're trying to push the boundaries and the mark, and be overtly sexy in a way that went a little bit too far. >> reporter: a staff writer says the photos crossed the line into the disturbing. >> we live in a culture where we're still trying to get people

to understand consent, and so to have an ad showcase something that feels as though it's not asking the consent of the person within it, it feels uncomfortable. >> reporter: we reached out to calvin klein for comment about the campaign. but they haven't responded. selling sex has always been calvin klein's trademark. causing a stir with brook shields back in the 80s. >> you want to know what comes between me and my calvins? nothing. >> reporter: to kate moss and mark wahlberg a decade later. >> she has freckles. that is correct come between me and my calvins. >> reporter: but getting noticed by millennials means brands are having to up the ante, competing for shares and likes. >> calvin klein is tapping into a world view of youth culture. >> reporter: the fashion features director at refinery 229 feels this campaign is driven

and directed at selfie culture. >> they are provacative and sexual, but the point is that they're flipping the conversation. it's sexual, but it's not exploited. it's sexual and empowering. >> so you think these ads bring a positive message for women? >> i do think that. this is already happening in social media. they're taking selfies in ways like this. it's them saying i'm feeling confident about what my body looks like. >> reporter: calvin klein pushed the envelope earlier this year as well with this billboard in downtown new york city. some called it more insulting than edgy. ? the woman is overtly sexualized. >> reporter: on one side a young woman with a tag line i seduce in my calvins. the other with the side i make money in my captions. >> i'm not happy about it. i won't give calvin klein my money. >> these ads are sexist. high zi zach who has her own

underwear company was offended. >> reporter: old jenner the stereo types that a woman is using her underwear to seduce and he's in his underwear underneath his clothes making money. >> reporter: she started a change.org petition to take the billboard down. >> i don't believe underwear has to equate to sex in advertising. >> reporter: the company claimed they removed the billboard as part of a planned rotation, not as part of the petition. in 2009 this billboard was in the same spot, insinuating group sex. ? it's a little inappropriate. there's kids walking by here. >> reporter: but selling sex has always worked. their revenue last quarter was up 20%. it now feels kind of ordinary to see an ad like this. it's for shoes, by the way. or this, selling burgers.

but what adds to the outrage for some is that the models look so young. >> the problem is when you have an upskirt shot of a model who looks almost under age, there's a whole other element of yuck and what are you trying to say as a brand? >> reporter: young almost under age looking models was a hallmark of american apparel. we got a personal tour of a downtown l.a. factory in to 12. >> you were shooting models made to look younger, and exploiting their sexuality. >> i don't see it like that. >> reporter: did it hurt or was that what you wanted? >> it hurt a little bit. it was silly. the problem is in the real fashion world they're taking very young girls and making them look older and it's completely contrived. >> reporter: he believed that

american apparel's models were authentic. >> there's the photographer. she shot these of herself feeling good in her jeans. i'm proud of that ad. she's the brand, the customer, she's wearing the product, and she's the photographer. this is american apparel. >> reporter: in recent years the company has run into trouble, he was ousted as ceo in 2014. the company later declaring bankruptcy. despite public outrage at many of their campaigns, calvin klein remains a clothing power house, and a pioneer in the world of fashion advertising. some say this ad is actually progressive, sparking a positive conversation for young people. >> would you call this a success? >> yes. i would call this ad a success. they spent no money, but it's going viral. everyone is talking about this ad, and everyone is talking about sex and sexuality in ways that people don't typically talk about it when they see an ad. and i think that it's forcing a lot of parents to have conversations with their

children. >> reporter: for "nightline," i'm lindsey janice in new york. >> next mum is the word. queen mum, that royal blunder and other hot mike greatest hits. ♪ over here, kids. you. here. in you go. thank you. ♪ ♪ ♪ ♪ ♪ ♪

finally tonight, loose lips sink ships or so the saying goes. and the damage multiplies when you add a hot mike. >> the queen of england apparently not impressed with the chinese delegation, but speaking to commander about last year's state visit, the queen caught on camera committing a royal oops. but she's not the to forget about a mike. that same day david cameron with this embarrassing moment while addressing the queen. >> we have some bleeders of some fantastically corrupt countries. >> these mike gaffes not exclusive to europe. plenty of united states politicians have made the same

mistakes. >> [ bleep ]. >> the potus himself no stranger to mike mishaps. this leaked off the record exchange during an interview where he called out kanye west for his behavior at the 2009 mtv video music awards. >> beyonce had one of the best videos of all time. >> he's a jack ass. >> some mike mistakes more dam ang others. in the series finale of the jinx, robert durst admits to killing his wife and others while in the restroom? >> killed them all. of course. >> reporter: it was american preacher joel ohstein who said will careful what you say. you can say something hurtful10n seconds.
