Done research on your casino and found out that you are not a new casino domain was registered in 2011 and you have one review back in 2018
Why now after all these years why register now and decide to promote on Bitcointalk, anyway I'm sure the Bitcointalk community will welcome you with open arms since I have not yet found a complaint against RioBet Casino.
