If a member frequently seems to be in the middle of the dumpster fires we find here, we'll ask them nicely to find a way to stop.
After a few times, we'll step up the message.
Eventually, we'll conclude that they're either unable to help it, or uninterested.
We want to have a nice, civil message board community here. Some people are looking for something quite different when they go to post things on the internet. That's fine. There are other places for that (if anyone needs a recommendation, I gather Facebook Groups are perfect for this). These people will either get it, eventually, and stick around, or they'll leave. Of their own accord or not.
