This guy I constantly see at random odd hours of the day and night, standing int he same place, sort of between the SW mailbox and the door; he always puzzled me. For some unknown reason it clicked in my head tonight: he can access both the mailbox, and the auctioneer (through the wall) from that spot.
I came to the realization tonight that he very well may be AH botting.
Without fail, anything you post that this guy also has posted is almost immediately, without fail, pulled down and re-posted 1 copper less than you have posted the item. Conversely, it appears that if you post an item below a "threshold" he appears to have set for that item, he immediately buys it out.
whatever program he is running appears to keep a certain amount of items such as gems posted. He never has less than 5 of any particular cut of gem on the AH, and I've sat and watched him cut a gem, then wave goodbye to the auctioneer through the wall of the auction house.
What is really awesome is the tool is doing it all on what appears to be his main.
What is the "best" way to ensure this bastard gets nailed?
