People who wax nostalgic about old Reddit forget that
CW: Racism, pedophilia
its most popular board was r/jailbait, modded by ViolentAcrez, who also modded subs called r/[n-word]jailbait and r/watch[n-words]die. Every time he rightfully drew fire for this, the site rallied to defend him. The Reddit admins gave him a fucking award.
There was also an entirely separate network of subreddits dedicated to hating black people. It was called the Chimpire, because of course it was.
