The regulars are very cliquish and will go on and on about their characters and ignore what non-regulars do and say. They will also gang up on you if one is accused of something and you don't have very solid proof.
Eh, only a small group of them really are. I'd say ten at most, but if they're being stupid/giving anyone bullshit for no reason you can expect most if not all of the admins to deal with it. Quite a few of the admins (At least me, and what I've heard from other admins when I'm around) DO NOT enjoy cliques. If a group of people are talking about how much they love each others characters, expect me to tell them how fucking stupid they sound. The latter I haven't seen happen often, but as stated I'd personally tell the people ganging up to knock that shit off.
I'm serious, I fucking HATE cliques. So god damn much, I've talked in admin chat multiple times about how much I hate them, and how we can't encourage them. I also hate any and all glorification of characters/players, including admins. I don't care how much you like a certain admin/player/character, most characters in this game aren't fleshed out and are simple one-dimensional personalities. You literally just pick a random personality quirk (Russian, alcoholic, crazy person, nice person, etcetera) and play that way, it's no big deal.
My admin style is one I try to impart on each admin, and every trial mod/admin. Don't fuck around, treat players neutrally regardless of what they've done, don't try forming a stupid cult of personality around yourself, and only act like a dick to bad players periodically so people can't assume you're a dick ALL of the time.
