Mostly duplicate Robert Munch accounts. Bobby found himself a pal with a little intelligence that figured out how to circumvent SD security to a degree and has been mining inactive accounts and turning some over to him. This is being looked into.
At any rate, I don't ban anyone, but stardock is within their rights to ban any individual at any time for terms of use violations. As its quite difficult to imagine Bobby EVER breaking the terms of use (on a regular, daily basis), there are pretty good odds there will be additional bans. heh... but again, bans carried out by Stardock employees.
