My thoughts about mass acct deletions (why you get several accts banned at once)
I'm a noob and know very little, but I believe computers have specific identifications that are linked to their hardware (whether it be hard drive or motherboard, I don't know). I'm pretty sure that's the case though. Anyway, I think cip is probably collecting this information, so they can delete multiple accounts at once. It would also explain why some people are deleted within a day or so after starting new accounts.
Obviously, I could be totally wrong. However, I thought I would share this with you just to see what you thought.
