We're not using sape in Russia for at least 3 years, that's totally old-school method.
99 % of websites are worth to buy links from were deleted from the system years ago.
IMHO, the only one thing why the platform is still alive is in their foreign customers that heard an old story about the "powerful' Russian marketplace or even get the link from fiverr or other 'Super' places.
And guys... there are plenty of "new" systems that replaced Sape's space on the market...
And (for sure) these places are not PBNs!!
