What I consider problematic is the fact these people will organize massive efforts on Twitter to ruin other people's lives because they posted wrongthink. They make the 4chan raids I've seen look amateurish.
Yeah, 4chan is toxic and savage, but at least they are honest and humane in a candid kind of way.
The cyber-bullying's of 4chan is trash though...
While 4chan posters occasionally get organized and manage to operate outside their borders, these incredibly malicious activities just aren't something I associate with them. They're the specialty of groups like kiwi farms who are responsible for the suicide of at least one video game console emulator developer. I was shocked when people told me about byuu's suicide here on HN.
