Honestly, it seems suspicious. 9,000 links for 300 rubles?? That's some kind of fantasy. I buy links on gogetlinks for 500 rubles EACH. In short, it's a total scam. In reality, there are many free promotion services, like pitcher.su - I did a free run of about 100 links there, and they appeared in the webmaster, but they don't really bring much benefit.
