Please note that I do look for people signing up for multiple accounts and will ban anybody I find doing it. I think the recent banning of one person using two accounts is a good example. I have found that it's almost always the trouble makers who sign up for multiple accounts because they know they're at risk for being banned and want to get in their parting shots, usually on a weekend since I often don't monitor the board then.
I feel sorry for people who get so wrapped up in this that they actually go to the trouble of creating fake web sites trying to make someone else look bad. What an empty life a person like that must have to have the time for such nonsense.
