Nowadays, anyone who plays SF4 online with have a disconnect percentage rating, but people still manage to slip through. Justice is served to such pricks in the form of Rage-Quitters.com
a website that names and shames quitters with screengrabs submitted by the cheated and disenfranchised. I wish I'd heard about this sooner. If it happens to you in future, make sure to submit and when you first visit, search for your gamertag. Only then can you understand the relief I felt at not being on there. Thank Christ.
