Have you ever heard of the site called Topix?
I've been there a couple of time. The owners claim that it is supposed to be the new news model, but a lot of the time, it's just racists, homophobes, sexists and bullying nonstop, frequently unprovoked. I've seen so many unprovoked racist posts that get so many likes.
Apparently, it garnered international attention because too many cyberbullies use it and ruin people's lives by posting slander since the site requires no registration and the site is legally protected. It apparently ruined little towns across the USA.
