I've used the Wikipedia username "LonewackoDotCom" since 2005 or before, and no one's raised any issues with that name. However, after a recent attempt to post the indisputable facts about the Obama citizenship issue to the Barack Obama talk page at Wikipedia, one of their users indefinitely blocked me, claiming that my username violated their guidelines. They don't allow domain names in their usernames. The message included as part of the block suggested that I change my user name, which I did.

More on this later.
