To paraphrase Shakespeare: I bid on a few Camillus knives on eBay - and have been bidding on several lately against a slew of same format screen names. ALL have 2 letters and three *** in between. All have private feedback. There are at least 15 I've noted bidding on items. Here's just 2 auctions with the *** bidders. I'm sure there are more. Check your own auctions and see if these characters show up? Maybe I'm just parnoid but this seems very odd to me.
