It's just an alias, and an alias is easily identifiable. I have many other people that use alias's that resemble my handle. I merely laugh it off. At one point, there was the alias that said McDonaldOOO and not Mcdonald000. Man, how far can they go, LMAO.

It's no big deal, because other viewers know that its only an alias, and its meant for teasing. If you truly believe that the person is trying to cause you hardship, then simply report it to admin.
