Banished From AOL for life?

Yesterday as I was having my morning coffee I received a phone call from my sister. She called me to ask if I was able to get on aol that morning because she was having trouble. Every time she would log on she would be immediately Booted off. She tried going through the internet explorer only to be told that her pass word was invalid. After a couple of hours I called her back to see what progress she had made and she told me that aol had band her for life. Wow, you could have knocked me over with a feather because my sister is not the type to do anything on line that would get her kicked off aol. As it turns out the violations were committed under my nieces screen name, she shares the account with my sister. The only problem is that on the days the violations occurred my niece was no where near a computer. She was up at my sisters cabin with the rest of the family for Thankgiving dinner. What we think happened is that her room mate whom we believe knows her password went online under her screen name, ooops. Any way my point is that now everything that is important on my sisters computer is tied to her screen name and is now no longer available to her. AOL says she can appeal in writing but that the chances of having the decision reversed are pretty slim.
