Yep it's fine using multiple accounts, as long as you aren't banned then use another one.
But even then, I think it is pretty lenient. If you don't carry on like a pork chop then mods have no reason to check your ip address.
Sooz is a person and a running joke on bigfooty and TLC. I'm not the person best to describe as I wasn't there when she first gained notoriety, but she's a bit of a laughing stock; saying Brad Scott is her cousin, attacking people, saying weird shit etc.
Permabanned yet always comes back, and it's pretty easy to spot her now. She'll have a north avatar, weird username and says something weird with little capital letters.
