For a while I did post a tremendously horrible picture of a disfigured man, under a title containing what I thought were keywords used by pedophiles.
So that's my suggestion.

I don't dare do anything of the sort these days by fear of seeing the police arrive here, thinking I'm actually sharing kiddie porn...

(I got the picture in question on rotten.com. -I'd browsed my way there after a friend's suggestion. AND I REGRETTED BADLY !
That little trip even kind of scared my off the internet for a few days. Nevertheless, I managed to save the one picture, thinking it could come in handy if ever I hated someone reeeaaallllll bad. And pedophiles are pretty much in that category.)
