None in my region, so I'm safe. But if these things are asking for personal information, making you buy things, or even just trying to get an e-mail, then that's bad. I've seen other similar 'fill in survey/offer get free access' deals, and they have been pretty bad and often quite obviously just scams.
I'm a bit concerned that BB would be hosting this. Are they that desperate to generate revenue from this game that they would do this?
