And you are sure that there's no deleting of your posts and comments going on? Because that might also be a cuase for your AP count to glitch at some point...
And admins and mods respond as fast as they can, but they do have other work here on ArmorGames and that means the whole of the community, not just one user in particular... unless you're someone trying to circumvent a bann of course, because only THEN admins become REAL good and close friends to you! =)
