Lately I've been hearing and reading threads over on the Xenforo support forums that are full of drama. Between people complaining about the fact that Xenforo relies on third party devs for lots of their plugins to people feeling like they're being ganged up on by staff I've seen it all. I haven't seen too much drama on other support forums, I'm sure it was more of a problem back when forums were still super popular. Xenforo is one of the most popular forum software and the support forums are active so it's no wonder why there's some drama over there.
