I believe most times casinos intentionally do that upon launch to allow traffic to flow in and when they start getting the traffic they desire, they update their terms of service and registered members would not know that until they want to make a withdrawal and the casino requests for kyc and then they would tell them that their country is on the restricted list and would get their account banned or suspended after they had deposited funds to play and won games. There was a time on this platform when cases of this nature were reported here and from findings, most of them were innocent as the casinos initially did not state their restricted nations and kyc as well but after a while, they secretly included it and did not inform their members using the claws of they changing their ToS on a discrete condition without the consent of the gamblers which the gamblers have accepted before signing on their casino.
If the casino changes its terms of service then suspends the account or even freezes the deposit, it will be a scam. They just mentioned Restricted Countries, and because they have not written it down then it is a shortcoming of their casino. This should not be a loophole but a part that must be fixed immediately. Moreover, they plan to launch a review campaign soon. There have been several points of discussion related to several shortcomings or inconsistencies conveyed by several forum members who pay attention to this casino. Just a suggestion for Betkin, fix everything first from the input given, and after everything is ready then launch the review campaign.
It can still be the other way round as they can launch the review campaign so that members here can help them find out more shortcomings and bugs to fix in the casino. What you proposed is also not a bad idea because I think a lot of error have already been noticed and if anything the casino should start from there also but since they already have a signature campaign running it kinda shows there are ready to work on things.
