However, we've had some serious concerns about folks blindly recommending them to people forum-wide without any explanation about the risks, since there are potential serious drawbacks when they're used: needing to activate through a VPN spoofing your region, UI being in Russian, needing to download an external language pack, DLC being region-locked by publishers, Valve contacting people asking for photographic evidence of the game box, and in some cases publishers removing the game from your library later on.
On top of this, BlimBlim reports that these sites also deal in stolen keys:

Back at the launch of a game we had the exclusivity on, we were naive enough to disable our fraud screening system, and got hundreds of keys stolen over a period of just a few hours. Just for a test we tried to by a key from one popular bargain priced key sites, and yep it was a key from our batch. The amazing thing is that it had only be a few hours between the fraud and when we tried buying it. It was easy to find since we were the only one in the world who could sell the product for one week.
Of course all these keys have been blacklisted immediately, so it could also be the case with these RU BF3 keys. I don't really know though.
We'll be treating these no differently from pirate websites. Don't link to them, don't recommend them.
