Service SearchFace.ru. Part 2.
From February 2016, there was a similar site called FindFace and was very popular. It was developed by NtechLab.
In September 2017, the company began to cooperate with the authorities, and on September 1, 2018, it disabled the ability to search for people on its website.
Most likely, SearchFace is the same FindFace only in a new wrapper: different interface, improved search algorithm, expanded user base, etc.
This is confirmed by checking the site in the web archive. It contains 2 mentions of SearchFace.ru for 2016, when you click on them, a redirect to the site occurs FindFace.ru.
Perhaps the developers did not plan to advertise this site, but simply tested the functionality of the algorithm. This is confirmed by the lack of HTTPS, as well as the crooked interface.
But in any case, Vkontakte did not like the idea of the site and they are already going to sue the developers.
Perhaps this is due to the reform of privacy, which was caused by a wave of criminal cases for likes and reposts in the Russian Federation last year.
It is noteworthy that a similar service vlicco.ru, which began working at the beginning of this year, published an appeal for a temporary suspension of work from February 14 for political reasons.
