> If you value your privacy, avoid using any Russian-based search engines or social networks if you live in Russia

Pushing this forward, if you so much value your privacy you should not use any service which has official representatives (official company behind it), because in many countries they should provide user data on goverment requests (e.g. http://www.google.com/transparencyreport/userdatarequests/RU...). This is a disturbing fact, but this is how modern society works. You should throw out the window all your electronic devices and move somethere to the North Pole to protect your privacy (and I can't guarantee that satellite will not watching you). "Privacy" nowadays is just a huge illusion which is an euphemism for the statement: "Somehow, you can be sure they will not come for you for what you doing. For now...".
