There are mods. They just have annonymity.
@ Kain: Ska2D2 is right. I know two players that are (were) mods and both are respectable players that cannot be identified in any way unless they tell you. I think that's actually a very good system.
As for clans: the ones I know are both in a (respectable) clan, but I don't see how that would lead to abuse of their powers.
I have no idea how much they can do and I don't care about that (nor should you). Warlight is and remains Fizzer's (and maybe Mercer's?) business, so he (they) deceide(s) how to run the site.
