I'm wondering if they have decided to do away with free rolls altogether. Sure has taken them a while to get them going again. Betonline, discontinued the two $100GTD they had just out of the blue, get rid of micro cash games, and make the minimum you could buy in for a cash game, $4. I might be wrong, but it seems like it drove away a lot of players.
There will come a time when online poker will be available to everyone in the US again. If ACR decides to discontinue free rolls, it is a good way to destroy your customer base, because players will be playing on other sites that are more stable, they like better; offer a better playing experience where software updates aren't sketchy, players are kept in the loop and not left guessing.
