I'd avoid wasting your time with bonusbitcoin after visiting the site as often as it allowed, I'd collected about 1 million satoshi, and verified there were no max limits on what i could withdraw or earn on that site, it threw up a very vague message of possible terms violation.  it's been over a week now and the operator will not answer emails as to what my alleged violation was, nor will they pay me the satoshi i'm owed.  Sorry I wasted so much time on this one!
