I don't know. Apparantly when the former mods left this group, they just handed out admin rights to random group members and hoped that'd be enough. So one of them is just... throwing a lot of non-40k art up and calling it a "crossover". I'm doing my best to reject it, but all it takes is one mod to approve it, so there's not much I can do without it becoming a power-grab pissing contest.
