I think you have to hit 2 others before you can go back to someone, i.e. if you hit Mr. A, you have to hit Mrs. B, and Ms. C before you're allowed to hit Mr. A again, and I think you can't hit someone more than 3 times a day ... or something like that, the details are a bit fuzzy. Oh, yeah, the Admins are limited to giving something like 15 points a pop. Otherwise they'd just hit way too hard.
