Not impossible, unfortunately. :(
Las Vegas does have millions of visitors, and casinos do have a harder task of keeping track of refused players, however, the same cannot be said in most of the other casino destinations in America.
Keeping track of all the, I don't know how many , thousands of players who play unrated in a big place and being able to retrieve all their back play same as a rated player, who gives you the key to all this info, would be an impossible nightmare.
Which is another reason that you are more likely to be hawked for a players card when you're betting green chips, as it now reduces the number of people to be tracked.
This would be like 1,000 times harder than keeping track of the backed off players and they are'nt all that great at that. I guarentee you that out of all my past anon. sessions the casinos have not ever be able to connect me to over 90% of them.
I will briefly describe a personal experience that might give you pause to that belief, but first, a couple of questions; 1)Were all the sessions you referred to at green/black and above? 2)Without being to specific, what [very generic please] % of sessions were LV/AC, riverboats, Indian casinos?
No matter what your response is to this post, you won't change my mind. Cellini I consider you hands down the MVP on BJ21 but I think you for some reason are making this refused name file sound much more easy and effective than it really is.
Maybe Cellini can't, and I'm not about to either, but I'll share some insight to why the refused name comments by him sounds credible to me, as I have experienced a rather unique situation that does lend itself to confirming what he has said about refused names and how casinos track them.
This may sound a little cryptic, so please accept my apologies here, but during the mid to late '90's I would visit a large store where huge spreads by all players were not only tolerated, but because the hold was so high, and the comps were non-existent, that many, many players never had players rating cards. Now, one would think, that full tables of heavy green to black and above, tables with "unrated" players would make the hawking of cards a top priority, but in essence, it wasn't. This always perplexed me, as I thought I was flying under the radar with all the other "non-rated" players, but the more I played, the more the pit(s) recognized me, thus never asking me if I wanted to be rated. Occasionally, a new critter would ask me if I had a card or if I wanted one, but only once, then I would never be asked again. Strange. Sometimes I'd get the shift manager, or the casino manager who stopped by and watched, but never backed off, and never hassled for a card. Again, strange. I wasn't the only one that experienced this, as there were many, many people [where one would think it would be too big a chore to track, and it didn't appear to be a big deal....LoL] who played without cards.
Then through sheer happenstance, I met at a party someone who not only recognized me, [but who truly, as I have confirmed over the years, despised the very casino where he/she works] but proceeded to tell the procedure by which the "refused name" system worked. Also, he/she was someone who I never really had any interaction with, so his/her information about me was very interesting, to say the least.
It is my belief, that if you play unrated at a casino often, [whatever that may mean] that your name is incidental to the casino. They know you, merely as, "the guy with the long sideburns, gold seiko watch, gold ring on left pinky finger, etc.. When you sit down at the table, they start a card, if unrated, they write down this info, and input it into the system. When they get a match, they "know" who you are. Maybe not your name, but who you are nonetheless.
If comps aren't important, anon play is fine. If they are, and you play where they can be substantial, then you are losing if you think that they can't track you based on being unrated or are less likely to be backed off, which is why, if comps have value, that the cards, as evil as they are, are the way to go, IMH and sad O.
