One note of caution here: I know that many players have found that opening an account at Del Rio ended their ability to register at Playtech casinos. I’m in the same fix. Upon registering at Del Rio, I was locked out there, and at all future Playtech casinos.
(Playtechs where I already had an account continue to work just fine.)
I think it would be foolish to send my visitors there, knowing that some of them may no longer be able to become players of mine at other Playtech casinos.
If there’s a problem with bonuses, then make it clear to the players in question that they are no longer eligible for Playtech signup bonuses. But don’t just prevent their depositing altogether. Remember, the casino has complete control over bonuses. Why would you blacklist anyone, unless they charged back or committed some type of fraud?
One of my best players is no longer able to open new accounts because of this. It’s Playtech’s loss, but mine as well. I think he has accounts at maybe 10 Playtech casinos, which is comparable to my own numbers.
