God, that seems like eons ago already. Looking back at my records I can confirm that policy has been in effect since at least 2008, which is when I marked my YouWager account closed and created a table for a BetPOP account on the same day. As I recall that was prompted by my own inquiry on precisely this issue, being told by their Player Services that I could only have an account at one First Fidelity property at any given time, though they had no objection to moving me between them so long as I did it through a support request and didn't just create a new account on my own and leave the other one(s) dormant.

As it happened the inefficiency I thought I had isolated with the BetPOP lines proved short-lived, if it ever existed at all; I wasn't any more profitable there than I had been at YouWager. Looking back now that seems more like a fait accompli, with First Fidelity having been in operation for over 20 years now...nobody stays in the game that long unless they know their numbers and risk tolerance, and run a tight ship to boot.
