To the OP,
I was looking at your completed sales, and here is a CJ that you sold that shows the same two bidders that you're questioning. So, I don't think they're shills or bots, they're probably just CJ collectors like yourself.
t***e was the winner of the item, so you should already have his contact information if you want to know who he is.
