Diamond Sportsbook?

Diamond Sportsbook? This book is rated A+ on SBR. Its software mimics Bookmaker's. SBR says Diamond and Bookmaker are in the same building. However, SBR also says Diamond is totally independant. What's the word on Diamond?
In the Bookemaker umbrella for sure and very very safe.
Does Bookmaker care whether players have multiple accounts within the Bookmaker family - i.e., simultaneous accounts at Bookmaker, BetCris, and Diamond?
They did not care in the past. As far as I know, US players can only use Bookmaker or Betmaker exchange at this point.

You can have both. They let you transfer funds back and forth. I haven't used Diamond in a about a year. I did get a popup message from Diamond them one time about double hitting props when I was betting them at Bookmaker and then at Diamond. Diamond cuts your limits pretty quickly. Kind of the same relation Betjamaica has with Greek. Diamond copies bookmaker lines for the most part, but they don't copy the openers, they wait quite a while.
Thanks to all for the responses.
