Porn viewers in Russia must now sign into online sites by giving over personal information

Russian visitors to Pornhub now have to sign in with their personal details and their passport. The Russian government has gradually been looking to make it more difficult for people in the country to access pornographic websites. That has followed shutdowns and criticism of the website, which state regulators said was distributing materials that were harming the development of children. The rules followed that complete shutdown of Pornhub, the world's biggest adult website, in September last year. That ban was lifted just months ago, when Pornhub committed to check the age of anyone who visits it. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph.
