VKontakte starts to cover illegal content?

Today I found out that Leningrad, Lyapis, Bi-2, Noggano does not find a search by audio data in a social network.
Apparently, they create a base, the search for which will be prohibited, and apparently the base will be replenished, while by the name of the song you can still find some songs, but not all.

I wonder what will happen next? Deleting audio content?

By the way, many startups based on searching for audio through vkontakt are not destined, for example worryaboutyou.com.

It's time to go to Facebook.

PS For me, with the advent of such innovations, the network loses its value, before that it seemed to me that vkontakt is the best player.
