I’ve received that message today. I’m from Belarus.

We noticed an issue when verifying your account. The legal entity information associated with your account fully matches a restricted party or one or more parties from the United States government's consolidated screening list, another government's sanctions list, or a restricted regions list. 

I know nothing about sanctions but I’m 100% sure that’s how sanctions should not work by discriminating developers from country which governments appeared in any sanctions list.

The same “surprise” from Apple without any warnings. How this can happen?

I am also from Belarus and my account was also deactivated today due to sanctions. But I am not in any sanctions lists… The deactivating was made instantly and without any warning, without any opportunity to find out real reason and opportunity to prove my innocence. I don’t understand the reason for this behaviour from Apple.

Exactly the same without any warning!

I’m also from Belarus, join all the above, my account was deactivated without warnings.
