Some other time, in my own thread, I'l post in my own Adventures the details of the circumstances leading up to my getting handicapped with the 3X spread. I have mentioned this probably a dozen times over at WOV - you must have missed it.
Now - is it possible KewlJ, that you were first put on a DNI (Do Not Invite) status and then the comps were cut off? In other words, that the action came from casino management to cut you off from blackjack, and then of course when that happens, casino management has the option of just letting it go at that or taking it further and taking steps to have you removed from the property entirely.
As described, my experience has been, for known rated players who have been giving the casino good action, is to cut us off from blackjack only, and tell us that we are free to play any other table games - and in such circumstances, casino marketing/hosts aren't even brought into the equation.
Now, it's a bit of a chicken and the egg discussion - because you mention the drying up of offers and comps, but is it possible that all that happened is that they decided to cut you off from their casino entirely, which would then of course as well cut off the comps, versus that they cut off comps first while leaving your ability to play blackjack intact.
People are put on DNI status for different reasons - and it's not quite the same as being 86'ed because they might still be allowed to walk through the property, but their offers are cut off entirely. I knew a guy who was put on DNI for chip hustling - he kept trying to get high rollers to bankroll him claiming that he had money but not with him. Another guy I knew got on DNI status for failing to pay his markers, in a situation where they didn't turn him over to the district attorney, for one reason or another, but somehow he ended up stiffing them and got away with it such that the statute of limitations passed and the debt was uncollectible. I suppose you could also wind up on DNI status for not paying your markers on time - paying them eventually, but very late. Etc.
