I've never heard about Bitcoininfo.ru before but after reading the article I visited the site. Idk maybe it's banned in Russia but it's working for me perfectly.
It seems that it is working for basically everyone. I have tried to access that site from all possible Russian proxies, and they all opened the site without any problems, so people in Russia should be able to visit it.
It could be that the owner of the site just doesn't care to take that site offline, which for me seems to be a great and an encouraging gesture towards the authorities. I however wonder how long he will keep it up.
That being said, Russian authorities have never really been a champion in enforcing their own laws and policies. While they put so much effort in such an insignificant site, there are thousands of sites not being affected at all.
