"They're showing up because someone made an offer for them"

my neg list looks exactly like Morgan's...and i am on a server with people with level 6 (i am level 4, Dreamer) so there are much better players available on the server so ours aren't the best.
Many of these players on the neg list are unbidded on. I just checked a 36 star guy, no bids. So he can't have shown up becoz someone just bidded on him (coz he's still on the neg list 10 min later without receiving bids)
