I did a search and didn't see any topics on this matter. But recently on a forum I belong to, a member that was banned several years ago has popped back up on the forum with the same username. Its the same person with the same username by the way. How is this possible? Doesn't the software home in on usernames as part of the log-in procedure and detect the person is banned or blocked. Or is it only IP address sensitive to the person logging in, and they can simply change devices such as tablets, cellphones or other internet capable products to log in and fool the forum? Would it matter what version the UBB software is?

Thanks in advance!
