My post doesn't suggest that I don't grasp the concepts of transactions and confirmations - to say so is beside the point (and insulting). What I didn't understand was Bets of Bitcoin's ineptness. I see your 'caveat emptor', 'screw you noob' mentality displayed much too often by the Bitcoin community (and technically proficient humans in general), which would be better served by welcoming and supporting those with less knowledge.
I don't dispute that the rules governing the possibility are in BitBet's FAQ (and in fact linked the rules in my post, which you apparently didn't read), but I do dispute that the
rule in question is a just one.
That the concepts weren't grasped was inferred from the suggestion that there is something unjust about the rule, and that a service has any obligation to remedy the fact that a user failed to include a tx fee. It's not meant as an insult, it's meant to explain to you how and why the steps you took were taken at great risk to your BTC.
What's the actual reason for BitBet to steal the coins in this situation ? "You're screwed", as it is written in the FAQ, is not a proper answer.
