Facebook suddenly decided to ease its restrictions on cryptocurrency promotion introduced in January. Starting from 26 June, advertising from approved advertisers is partially permitted.

"In the last few months, we’ve looked at the best way to refine this policy — to allow some ads while also working to ensure that they’re safe. So starting June 26, we’ll be updating our policy to allow ads that promote cryptocurrency and related content from pre-approved advertisers. But we’ll continue to prohibit ads that promote binary options and initial coin offerings," the social network wrote in a statement.

In order to achieve prelimenary approval, advertisers must fulfill an application so that Facebook could verify that they meet their criteria. In particular, the company may be required to inform Facebook about relevant public background on their business, including any licenses they have obtained, whether they are traded on a public stock exchange, etc.

Given that ICOs remained prohibited, Facebook urged users to report if they see violation of the advertising policy of the social network.

Facebook became the first major company to ban advertising of cryptocurrency projects. In early March, Google announced similar measures, and on 27 March the ban on ICO projects advertising came into effect on Twitter. The new Twitter rules were the closest to today's Facebook policy. Then the microblogging service announced that the restrictions will not affect the companies that are registered on major stock exchanges or (for example, in the case of Japanese crypto-exchanges) licensed by the national financial regulator.
