From my own personal experiences, once a property has determined that you can in fact beat them, they will drop you off the comp list for any blackjack freebies. If you have a second game like video Poker then they will allow you to play and earn points. I feel like it's like going to golf resort but they only let you play shuffle board or tennis...why go? With that said, after a 6-8 months layoff, I have never experienced any property that has good enough facial recognition to pick me up when playing and in fact have been backed off multiple times at the same properties without giving them my real name. However that normally earns me an escort off the property. The back offs are chain wide if you use your name/players card. In my opinion a disguise is not needed. Remember, the proliferation of casinos means we all have choices, not like 30 years ago. Ask yourself if you are there for the money or the freebies. Yes, freebies are an added value but if you can't use a players card then you must ignore them.
