I've just received a spam from Las BitVegas sent specificly to the unique address i had on 'Gox during the time the database was leaked. If they're shady enough to spam emails from a leaked database i definitely wouldn't trust them to be fair at all in gambling matters.
edit:btw, i wasn't sure where this would be best suited so i just posted in the general section, please move it to where it would be the most appropriate if necessary.
