Signature members are now doing the advertising for the site? Not like this is a shock watching this thread over some time but you think they would advertise their own promos in their own thread. I think a site suffering from optic issues would be more on the ball. Add the issue with the dice that people are addressing here and I think I will pass.
If you are not interested with it then you should just skip this and just walk away. There is no reason to skip this kind of promotions. You do the math, this is totally +EV so most if not all will end up in profit after achieveing the requirement for the wagering, and of course all those issue you mentioned are most solved
