Are you affiliated with coinpoker because you're giving free roll or it's their promo alone?
If the freeroll is password protected then it is high likely that btcjack is the one who create the freeroll. It is like a collaboration between the poker site and btcjack. If the poker freeroll is created by the poker site alone then it should not be password protected unless the freeroll is open for specific players only who have made some rake on the site.
