Paleohacks is a participatory site. If you truly believe something is offensive or counter to the FAQ of this site, please flag it. If you have enough points, you can vote to close a question. The moderators are different people with all sorts of different levels of involvement, so we can't often catch bad things in time and sometimes things are borderline and we aren't sure whether or not to delete them. If we vote to close, things automatically close and never get any community input. We do delete and close a lot of stuff though, mainly obvious trolling, ads, and things that are really really obviously offensive. But we miss things too.
Also, the site will automatically close or delete things if they have enough flags or votes to close (I think it needs five). It's magic and it's great for us mods since we don't have to do anything, but it requires your participation.
What doesn't help us is to answer the question with complaints about the moderators or about the site having questions you don't like. That's not an answer and that doesn't make the site better.
UPDATE BY PATRIK: If you haven't read the FAQ -- please do.
Edit: also if you are mad about something being closed, you can vote to reopen!
