The question is what REAL harm could have come to Tills? Oh so what she saw some pictures, if she didn't like it she could easily have blocked Nick, they weren't going to meet up or anything like that either. Also to correct you, according to Tills she did lie to Nick about her age for a significant period of time before telling him, granted from her account of what happened she told Nick sooner than she told everybody else but she still lied to him about her age for a long long time nonetheless.
By her own account, she told Nick she was 19 for a long time, as she told everyone else, yes.
But then she told Nick she was 15, and then Nick sent her the images.
And it's not even about what harm would have come to Tills (even though it's known that Nick travels to meet forumers frequently, and also has difficulty keeping things to himself, had she ever reciprocated in sending pictures).
It's the fact that there's a guy here with such dangerously loose morals regarding his interactions with minors. This is a game where the average age of players is about 14.
Also stop loving throwing the word paedophile around.
"child enthusiasm or paedophilia is a psychiatric disorder in which an adult or older adolescent experiences a primary or exclusive loveual attraction to prepubescent children, generally age 11 years or younger." -Wikipedia.
Wikipedias definition of paedophilia is not the same definition used by the various laws around the world.
But if it makes you feel better, I'll just refer to Nick as a loveual predator of minors.
