it's not feasible. But it's not the point for Russian authorities, otherwise they would have to ban a lot of different sites: a) any Internet store - like Amazon, Ebay, AliExpress you name it, as they all hold some 'private data' including name, address, cc info etc. b) any booking site - same as Internet stores c) any website which deals with Russian citizens - e.g. foreign embassies :)

so the point is to try to block a big Internet entity and check if there is any backslash, any reaction or any anything :)
