Damn! that is harsh and very very big issue .
It's nice to see that the fee will be returned but that really scares the shit out of me .
I will not touch the custom fee adding function ever
Same here. Its really great of bitman to work out with the guy to get most of his money back, even though it was not their error. See we have some good people left in bitcoin!
Well wouldn't this be essentially be robbing the miners who are mining on their pool? My understanding of a pool's relationship with the mining utilizating their pool is that the pool is to distribute all of the mining revenue (including tx fees) to all of the miners with the amounts being distributed being based on the payout method. Just because someone makes a mistake in creating a transaction does not mean that the miners are not entitled to all of their income.
Although it is very clear in this case that the size of the TX fee was a mistake, it is difficult to draw the line between TX fee that is intended to get the transaction confirmed quickly and an erroneous transaction. As per the Bitcoin protocol the transaction was valid so IMO the sender should bear the cost of their mistake, be held accountable, and learn their lesson.
