I have had direct content with somebody who had been harassing me for several months, and who had exploited my old IRC account. He told me recently he was %1, and his actions and behavior fits the description.
Assuming the person I was dealing with is %1, he already claimed to have an alt under another username that he told me. He has two active BLIDs.
I think he wants the attention. He was trying to provoke me to post details about his alts recently, by whoring me on Steam. It seems a bit too much of a coincidence that his name suddenly appears now.
Something to think about. I think %1 is a concern as a player, because he enjoys causing trouble and watching the reaction. He makes for an interesting conversation though.
