And lest we forget the good times on the now defunct example.com?q=.

Hall Monitor Bippy would stay up all hours of the night trying to find my socks. The site had a glitch, so every-so-often you'd get an account with unlimited rep dispensing. Some guy named Duck615 and me would neg rep Benson, Phoenix68, Mike, Vegas Giants, Pastafarian, etc. 100 negs at a clip.
You could almost perform neg repping macro style, so I took Bippy from +4700 down to 2900 in a sitting. He went totally ballistic. I made another account with the same glitch. I was going to put Bippy in the negative, but that's when the site shut down. Ah, it was good whilst it lasted.
