I'm aware that almost every registrar has similar terms. However, according to ICANN's registrant benefits and responsibilities page, a registrar can't just take someone's money away. To quote Domain Name Registrants' Rights, Paragraph 3

"You [Domain Name Registrant] shall not be subject to false advertising or deceptive practices by your Registrar or though any proxy or privacy services made available by your Registrar. This includes deceptive notices, hidden fees, and any practices that are illegal under the consumer protection law of your residence"

IANAL, but I'm quite sure that failure to render services for payment counts as an illegal action under consumer protection laws in Russia and elsewhere.
