Alright, as promised here are the rulings toward these above-mentioned issues:
Firstly to address Gman's inquiries.
From what I understand, you can be as ignorant toward other players as you want. You are allowed to abase and discourage them, so long as it doesn't involve excessive language. At this point I think it's safe to say that trolling is alright as well. (This might only apply if you have a reserve slot, so don't quote me) Swearing at other people might result in a kick or something, if it bothers the admin that's on at the time it occurs.
Regarding IJ's inquiries.
After a bit of discussion, the following is almost unanimous: You are allowed to call anyone you want retarded/gay a fag/faggot/retard so long as it's not in an offensive context. (Your guess is as good as mine) If you use it too much, you might get a warning. I think. Maybe. Be careful though because dropping an N-bomb is still an instant ban. Unlike every other derogatory term, this one is inherently offensive. (Do not ask me for the distinction)
As a side note, I have removed myself as an admin on the server. It may, or may not have to do with the pristine decisions above. I'll still be around the server now and then.
