And what's the problem with "I can bid on my player" ?
If the owner bids on his player, tough luck for you. You keep bidding or you accept the fact that he is either a jerk or in real needs to keep his player and search for another player.
On his end, he will lose some money (taxes) and those taxes will be like it's a new player. He is losing something, you don't.
Are you one of those people that moralize only about things they find "important" to them , but other things that are not so "important" can pass in all directions ?!
Daytrading is not good (I can agree in some points) , but raising profit with your own bids is ok.
Its not ok , if you want certain sum to get , then put that price , not starting from low price to catch the potential buyers and then try to extort more money...
I wont lie , I hate those people and as soon as I notice that he/she is biding for his own player I stop biding , even if I need that player badly.
