I would report any person that asked me to pay out of escrow before receiving the good as a scammer and you deserve to be marked a scammer for that.
You offer your goods with escrow to exactly leave it to the discretion of bitmit to decide if you or they get the money in the end. Changing that rule after somebody spent time (and risked to loose their money to bitmit "getting hacked") is exactly what bitmit can't accept without rendering escrow pointless.

To not have to change the rules after somebody accepted your deal, maybe state that you ship only to the US.
