And yeah, I wish bounty hunters would all vanish immediately and all at once. I find it hard to feel true pity when they don't get paid for their spamming. On the other hand, what's fair is fair no matter my feelings toward their line of 'work'. If Murat was supposed to pay them, then that's what he ought to do.
That thread is mostly filled with newbies applying to join the bounty campaign. It would a complete guess in trying to work out how many were farmed accounts but you stated an important aspect: the bounty manager should have paid in time he participants expected to receive.
If the fees to send bounties made it a loss making transaction then he really should have thought of some alternative to present to participants or better still he should have let them know from before they signed up what he would do to compensate them if the fees became too much while their bounties were too small to make it a viable payment.
