How long has Wikipedia been in existence? 25+ years? In all that time, I never once made an edit. Then, on a page for I knew something about - a Trade Union I'm a member of that shall remain unnamed - I recognised a factual inaccuracy. So I decided to do the right thing and make a very short edit to correct it.Next thing I know, my account was banned for I think four long years. If that isn't a clear sign that the information on Wikipedia isn't trustworthy, I don't know what is.
