That is, you can be cut off at one office and you can't bet here. But I do not know exactly from which company this has spread, and I do not know if they are blocked by ipi or by email address.
As for betfury, I have information from a Russian-speaking forum from a user with a good reputation. The user is most likely from the Ukraine, just like me. That is, not from Russia. I have information that some companies do not take kindly to the Russians and block them. This information is on the Russian-language forum, if you want I can give you links to posts in private messages.
What happens is that odds providers profile players. If you are limited or banned from one book, you'll have the same restrictions at the other books using that same provider from day 1. As an example, Betcoin has 3 books in one that use different odds providers. Limits will be different at each of Betcoin's books.
If there is some type of proof showing that wagers were treated differently on the same bet, Betfury will definitely be downgraded. I would need screen shots of winning bets cancelled along with losers accepted. After that, I'll contact Betfury to get their side.
