What if you have several people who wish to maintain their own accounts, all under the same roof? It's likely that you'd be sharing the same IP address, through your firewall.

I'm not saying you're wrong, I'm just saying that it's a problem for users behind the same firewall, or using the same computer. Also, for dynamic address situations, like with dial-up, or just turning off your broadband modem for a while, this method of regulation would not work.

Thanks for the input! It is likely that the accounts were from the same IP. I signed off, and they immediately tried to sign up. Hopefully we can work around this, and it wasn't something else.
