Time to update the list I guess, as far as I can see there are at least 2 casinos that can be removed/deleted from the list.
Playbetr due to they are now no longer running as they are redirecting to the new betcoin.ag site, and the 2nd site is 777coin since the casino is down/offline since August last year.
For 777coin, I dont think they will come back in the near future due to the fact that the owner is also no longer active in this forum.
I havent checked all your other gambling related topic, but if 777coin is still listed in your other topic, it is the time to remove them IMO.
