Hey guys, I run a Telegram group just for guro/gore art. Basically everything is allow so long as it's fictional, no not real life gore. You can join here:https://t.me/joinchat/Cnh5BUKJAMkI98wOCQDAbQ
It's not super active, though I'd like to change that. There's also a Discord server, but it's hidden, since Discord doesn't allow guro/gore content at all.
