Two thoughts:

a) Women get online revenge in other ways, so I'm a little odded out that only an angle typically exploited by men is being explored as problematic. Where's the article on fraudulently claiming someone's a pedophile? Telling everyone's Facebook friends he's got an STI? Calling him a cheater to thousands of people? Telling everyone he's lousy in bed and has a small member? Hijacking his Facebook and locking him out? Masquerading as him and signing him up for gay porn sites? Contacting his employer to smear him?

b) The primary vector for these young men to even obtain these images in the first place is the massive volume of female generated nude selfies. I've yet to read a study on sexting or nude selfies that doesn't show huge majorities of these images being generated by women, specifically to use to solicit male attention, online. Is this a 'live by the sword, die by the sword' situation?
