I have NO idea, but I can tell you this much... I didn't see anything in her posts that merited a banning, so I can only surmise that she was banned AFTER somebody hit abuse and it was determined that her's was an ISP returnee from the land of ZOT.
When you click on her screen name is says the account has either been suspended or banned. We will have to wait and see if 'gingersnaps' was only suspended or not.
