Sorry to post on an old thread. I was playing blackjack the other day at Borgata. I have a black label card there. I really haven't gone there a whole lot, maybe once a month. They did email me a free room offer about a month ago which I used then. I was betting $25-50. After 2 hours I was down $500. I got up for a second and 2 suits were behind me. They asked me if I was so and so and for my ID. I didn't really answer them and said I don't have it. They said it's required to have ID when in the casino. I grabbed my chips and they said well if you don't have ID then you can't play. So I left. I had previously played there rated fine and was receiving several match play offers a month. The next day I logged into my account and all future match play's were deleted. Apparently I am still invited to go to the comedy club complimentary. I'm not sure about my comps. I only have like $15 anyways so I don't really care.
I think that what happened was the MGM and Borgata systems merged and I was flagged in the MGM system.
There was perhaps other things going on that I wasn't aware of that I don't want to mention on a public forum. I wasn't counting (who would count there with their rules?) I may or may not be flagged in the MGM system. Let's just say that while the Mid Atlantic casinos don't seem to use databases, they are quite chummy with each other.
I did receive an MLife card in the mail from Borgata the other day. It has a different card # than my current MLife card. But for now, I won't be playing rated anywhere for some time.
