Well, to be honest, both approaches don't sound attractive to me. Because in both cases we'd block (and punish) our readers, not the copyright violators. The results would most likely be the opposite of the intention: instead of coming here, russian readers would navigate to lens-club.ru instead.

I'm afraid we'll have to check the available legal options if Sergey Borodin does not stop the copyright violations himself.
