Sharing players information

[treyster]

Does anybody know if certain casino chains share their player's gambling history with their competitors?

I have never played or even stopped in WinStar Casino in Oklahoma and now I am getting offers for free play free food and free rooms.

How would they even know if that might interest me unless another casino that I've already played at shared that information with them.

Is this common practice?

Are you absolutely sure you never stopped there? I thought I remember a post from you years ago you stopped in there on your drive to TX.
