From BBS I'd expect an answer like: "We don't allow self-bids; if you are worried that your player will be sold under market price, you shouldn't list him for 1k."
he simply wanted me to pay more by using a cheap shot. What can you do to prevent that from happening?
In this case users might want to self bid after something happened that they couldn't predict or control (not human error) - such as other player getting inj and making the sell not worth while.
Isn't there a "confirmation" button before you recruit someone? (Long time since I was NT manager)
