And lastly, for restricted countries, just use a VPN, we do not mind.

you could put this in your TOS to avoid that in a few months someone from a restricted country appears who has used your site using VPN and then your casino blocks his account and when he does KYC you accuse him of using the casino in a restricted country something against your TOS, but if you put in your TOS that people from restricted countries can use your casino and can use VPN then you won't have any problems in the future.
But I have a question:
if you allow people from restricted countries to use your casino, couldn't the country that issued your license sue you or even strip you of your license? Wouldn't you have problems with the regulators of several countries that put these countries on the list of restricted countries? It seems to me that they take these laws very seriously.
Thing here is t hat you do the basic things which a business must do.Its not surprising that majority of users here
will really be recommending to run off a campaign or any promotion or signature campaign.
Of course, most people will recommend running a signature campaign, the casino has cryptocurrencies, this is a forum about cryptocurrencies, that is, here in this forum are potential customers, knowing that many people on this forum spend money playing games, then run a signature campaign a good idea if it is well planned, let's look for example at this ann thread, if you had to signature campaign in this thread there would be many posts from the participants of the campaign and it would be talking about casino games, that would be a good thing

The updated TC's will be online by Tuesday, just finishing the translations, the EN lang version is ready to roll.
As for the restricted countries, this would go beyond the scope of this one post and there are many details regarding the legality of matters, but payment methods are causing even bigger friction. Keep in mind this is never a static matter, things change dynamically all the time.
There are some absolute no go areas like the USA, or for Curacao licensed casinos, the Netherlands and former colonies and current territories are taboo, as well as France. And off course, doing any sort of business with OFAC countries would be the worst offence that anyone could commit. You have to make sure PEP and sanction lists are checked and many more things.
The regulator frequently let's you know if some boundary was overstepped, when it is all said and done, the level of enforcement of the laws is the deciding factor, some countries (usually the small GDP geo's for some reason) have all the laws, but do not bother to enforce much or at all, while others are doing a very good job. Casino operators will follow the path of least resistance usually, we cannot disclose on how we decide target markets, but rest assured, it's dozens of factors that are considered.
And finally, as for sig campaigns, we have finally received an interesting offer and passed that to the affiliation team, I am positive it will get a pass, I have approved it.
Have a very nice weekend.
