Don't think that we're not aware of it as well. There's already multiple threads going for 3 pages long each or so in the moderator forums of us discussing what we can do about it. It's just hard getting the right balance between getting order here and consequently over-moderating, and letting things simply descend into utter anarchy. Either extreme isn't good, so we're currently in the process of trying to get that balance back somehow.
Also, most of the mods are uni students as well, so it does get harder to really be on the same level to some degree. Still, if there's any particular incidents that are actually troubling you or were the impetus behind this thread, PM me or another mod and we'll see what we can do about it.
