So, it's under the same management.

I think @Pmalek perspective, he only want to add the most recognize casino in-bitcointalk. At least have some track record experience from the member of this community, I also check the casino you're mentioned (Club Riches & dPlay). They don't have their own bitcointalk thread.

So, it's better to stick put listed the casino only from bitcointalk forum even the casino have some connection with Freebitco. It's just my 2 cent.
