The Federal Service for Supervision of Communications, Information Technology, and Mass Media (Roskomnadzor) blacklisted wechat.com, the website of the most popular Chinese messenger. As of May 4, ISPs are required to block all IP addresses and technical domains associated with the site.

According to VC.ru, some users have already complained saying that the blocking has cut off the messenger itself.
The reason for the ban was violation of registration rules for information providers.

Earlier a similarly worded reason was named when Zello, Line and Blackberry messengers got blocked in Russia. Zello stated that it was not going to register as an information provider because of Yarovaya’s law on data storage.
WeChat is the most popular messenger in China. It had nearly 900 million active users at the end of 2016.
