I'm just wondering...
If one person was banned for some reason, he could just create a new email and account altogether. And once THAT account would be banned, he could just do it again consecutively, abusing the other members of the forum. It would be "Create account, abuse person, get banned, repeat step 1."
For example, I was banned for supposedly sending CDchan a death threat. I have created a new account. The question is, what should the administrators do about it?
