Chinese regulators are blocking crypto-exchangers accounts in local social networks. According to Chinese media, in particular, the OKEx crypto-exchanger account is blocked in the most popular WeChat messenger.
The reason for the blocking was the violation of Chinese law: after the ban of ICO, the Chinese company OKCoin transferred its trading platform abroad, but continues to serve customers in China through the OKEx site, including through social networks. Regulators also are planning to block the IP addresses of foreign crypto-exchangers.
It is noted, that today the Russian Internet giant MailRu Group announced that in the social networks VKontakte and Odnoklassniki one can pay for advertising with Bitcoin and Bitcoin Cash. In turn, Facebook in late 2017 banned advertising of cryptocurrencies and ICO because of the large amount of scam.
