technically, it's whoever pressed the "ban" button, regardless of who saw him first, or who called hax first. The first to ban is the guy taking responsability.
I would assume that some other admins dont want to worry about creating a formatted report,,, so they just leave it to whoever else wsa on the server that has more demos...
it happened before when a friend posted my ban because i asked him to, only because my demo fucked up, but that was in the old days ,before the new admin systems.
I would assume right now that everyone should post their own report of their own demo since it REGISTERS ON THE FORUMS AS A BAN YOU MADE.

Fallen , fyi, u might be doing people a favor by posting their bans, but in the later run, if u decide to apply for any position in ibis, u will be asked to post all ban threads u made, and if some of them are not urs , and were overruled, then basically u are taking the "count" for wrongful bans as opposed to other admins who just filter their own stuff and forget about those.... it happens, just some heads up.

Thanks for pointing that out ninja
