What a great thing you do, heh.
Yes, I'm from Russia, too. I've got several 2nd level domains in .com, .net, .org and .info, and I'm used to use services from registrars like namecheap, actually I was using namecheap for a couple of years in the past. What I never did is, well, I never used these .ru and .su, it is obvious local government can do anything to 2lds under these tlds. BTW, it is much much simpler to run a site, or whatever, under these tlds when you're in Russia, you can pay in local currencies, you've got consumer rights protection, you don't need to understand English (yes, many people here don't understand English), etc. Pro-putin people mostly go this way, why they would do anything else. If you're "patriotic" (in that special putin's sense) you wouldn't prefer services provided by foreigners over those available locally in Russia.
Who do use your (or other registrars like you) services are those who don't want to enable putin's secret police to shut down their sites. In fact I doubt you can find a single pro-putin russian among your customers. Those pro-putin brain-washed "patriots" mostly don't speak English and (heh, yes) don't fully understand what is DNS how the domain names work.
The people you strike at -- your customers from Russia -- are mostly those who protest against the war and get arrested by putin's police. And as of now, with all the sanctioning mess, many of them have difficulties with their bank cards, and those who only have their bank accounts in the local currency, also have to pay the transfer fees at horrifying conversion rates.
Great shot guys.
Fortunately enough, I left your services and went to another registrar several years ago.
