This new rule?
http://www.usmessageboard.com/annou...lines-for-giving-out-negative-reputation.html
Rep is back to 20 in 24 hrs (I'm glad about that, 5 in 24 hours was really a small amount, imo) ; negging the same person more than once in a 48 hour period will get you whacked. Permanently, no exceptions. Seems pretty fair to me.
I never understood serial neg repping anyway ...
They said they'd take all your rep away and not give it back. You can stay though.
