If they have tiered KYC levels, such as LV.1 -> phone number, name, etc. without asking users to upload documents and selfies, that would be nice.
In many countries, such as in Russia, it was until recently possible to buy SIM cards which were not registered to a specific person. They were not even sold on the black market, but on regular public marketplaces in huge quantities.
I don't think that passing the first level makes any sense for a gambling site.
