I will be trying this one shortly.
I will be taking care not to trip up on the sneaky term (see above).

It's this one, neatly buried:-

* In the event that you have not made a deposit at this or any other Casino Rewards member casino, you may not redeem more than one sign up bonus within the Casino Rewards network, regardless of the individual casino offering the sign up bonus.

In plainer English, this means that the system will lock the rewards account if you take two consecutive new account deals without making a deposit in between to an account you already have. This trip seems to happen when you violate it and WIN, tripping on the cash-out. There is no reason why this "intervening deposit" need be greater than the min, although $50 might be better. Play through once or twice, preferrably in one of the promos for VIP points, and then withdrawn without bonuses. After this, sign up, check that rewards account is still unlocked, and get the bonus.

They are being really polite to me now, and ANSWERING EMAILS ON THE SAME DAY!!!!!
Perhaps I should start a new competition, guess the date when Casino Rewards lock my rewards account again. If they don't for a year or two, I might consider them "less disreputable", and they can leave my own personal Rogue Pit, leaving poor old Warren on his own!
