On my server, it's only really specific people consistently, and on most part, it's trolling or people not being able to tolerate ignoring certain people. There are some real grudges that people have against others on my server, mostly tied to a certain event. I feel as if certain events made two of the major groups wall off each other quite a bit (for good reason, I suppose. depends who you ask). Some people in my server are people that don't really seem to understand when too far is too far, but I like giving them a fair chance since I don't believe that most of these people are actually bad. I can't say I hate anyone, though it is hard to trust certain people considering unreal reactions to certain events.
I do wish the server was merged so I could join a group where I had no connection to any of their drama, even if the connection I have to my server's drama is not very direct. I still feel su*ion/bias from people based on whatever vague association I may have.
