Boat "VKontakte" indicates someone from friends was Pornhub

Programmer Daniel Suvorov wrote an unusual robot for "VKontakte". After processing the data PRNHB tells you how many of your friends logged on popular pornosayte with Russian IP, and will send links to their pages.

Bot does not work with closed profiles, and users who have hidden friends list. Also will not be reflected by those who use the VPN.

To start enough to write in a chat with bot the word "friends". Hunting is popular, so I have to wait a few minutes in line. Social Network tried to block the developer page, through which it receives the data, but the boat has already restored the work.

update: Representatives of "VKontakte" reported that closed this possibility:

To protect users' information we abandon the method of API users.isAppUser. Already, we have made changes. Now it is impossible to know which applications are installed friends VKontakte - including if they use the widget to login to other sites via the VK.

Revised Layfhakera get the answer could not be from the bot creator.
