that's not all i found, it turns out that Luckyblock.com casino doesn't have a good reputation on trustpilot, there are many complaints against them on trustpilot which leads me to think that this casino is another one of those casinos that have a sober behavior, they keep doing it selective payments to stay scam for many years. you can see the complaints against them on trustpilot here:
I'm always amazed when this comes up. OP knew about bitcointalk and a gambling section here. There's so many casinos advertising here and most are completely legit. If you keep stealing from people you eventually lose trust here and with it a chance to advertise because people who do will get red trust. With all that in mind, OP chose a casino that nobody here uses and that has a lot of negative reviews on other sites. Why would you do that? Don't you value your money?
Also, if they say they'd give your money back if you did KYC, why not try that route? You should have expected KYC when playing there. Most casinos perform random checks.
Are you afraid they'll find out you were really playing from a restricted country?
It's sad that people are playing at the scam casino's and therefore scam casino's business is still running. If everyone only opt to play at the reputed casino's then these issues may never arise.
Coming to the OP case, he was not willing to do the KYC. There may be number of reasons for this but if the reason is that he belongs to the restricted country where the gambling site have prohibited gambling, then for sure he could not get his funds back even if he does the KYC. Then another question arises as why he was playing on that gambling site from a restricted location? Again this is the gambler's fault.
