Can someone explain what is going on? I have NEVER and I mean NEVER done anything malicious while on Wikipedia, especially something to result in a TWO YEAR BAN? Someone has me mistaken. I have only edited a Wiki twice in the past 10 years and have no idea what is going on. I noticed an error on a page and was planning on helping out and was greeted with a 2 year ban. What exactly did I do?
