There is a new thread by this title at WoV in the last few days. At first read, I thought the OP was referring to the databases. But he specifically stated that there is a list written each day by surveillance, of AP's to watch for that day. I have never heard of such a thing. It seems like it would be redundant to the databases, which are lists of players that the casinos have paid subscriptions to.
I don't know anybody working in surveillance at the moment, but I did ask my friend who works the pit of a strip casino. He was not familiar with what was described. About the closest he could figure was his casino sometimes receives a list of descriptions of players, or more so... teams of players, to look out for from one of their sister properties in the chain that had issues with such players or teams. In the old days this was known as being "flyered" and it went out over fax machines. (remember fax machines? )
Anybody not just trolling, familiar with what is being described?
