I've never edited a page before. I once commented on the discussion tab that a page was not up to date, and that's all I've ever done. If I was supposed to put that somewhere else I apologize, but nothing malicious was meant by it at all.
I noticed a page today was not up to date so I wanted to quickly fix that. Before I could type anything I was banned on the spot. To address a ban you have to make an account, which I cannot do since my IP is banned. I'm not really sure what to do since I've never done anything to warrant a ban for vandalism.
