The most toxic communities I know of are the Genshin community, Payday 2, FFXIV and source games communities in general.
Eve Online where, as long as you’re not telling your victim to use real world money to buy things before you scam them, anything goes.
The thing about EVE is that caveat emptor is the social contract, and as long as you don’t get your dander up about being pirates or scammed, the “bad guys” are more than willing to help you learn to avoid the next trap. I was once part of an “anti-piracy” roaming fleet that got bored with the quiet night, and ended up jumping a newbie who was hanging out where they shouldn’t have been, tackling his ship, and proceeding to ransom it back to him for the princely sum of 1 ISK while we laughed our heads off in Teamspeak. Then we sent him on his way with a few hundred thousand ISK extra, some pointers on highsec versus lowsec, and the valuable lesson that there were always sharks on the prowl for easy prey.
