Yeah, there aren't any screener questions before you get on a rando group. You might get people you vibe with, you might get someone that is trying to use chamomile instead of Phenobarbitol to treat their "condition". Personally, I run a discord server with a general chat and a bunch of voice channels that my social network can use to game with because in-game voice chat with randos is just not fun to me the overwhelming vast majority of the time. It can be, but it's rare. I did the same with a Teamspeak server back in the day, just let it run 24/7 so anybody from our groups in various games could log in. I am sure most of you did/do the same thing. My gaming time is just too rare these days to waste it with idiots.
