Wikipedia is always up to date and I believe it's a fact. I also think that Russia doesn't really make bitcoin illegal but they only just regulate bitcoin to avoid money laundering. That was the last update I'm read somewhere here I guess. And so I think this site is legit, so you can exactly see it here. Also let's just hope bitcoins illegality will soon get revoke on some countries in the world. And don't loose hope if this currency, bitcoin, is illegal at your nation, they will soon accept it, believe me!
