The head of Facebook mark Zuckerberg said Friday that the company will prohibit hate speech in ads on the social network, and will also be tagging posts that may deserve attention or to be valuable to the public interest, but it violates company policy.

"We are expanding our policy against advertising to prevent the claim that people of a particular race, ethnicity, nationality, religion, caste, sexual orientation, gender identity or immigration status pose a threat to the safety, health or the existence of other" wrote Zuckerberg on his page in Facebook.

In addition, Facebook is expanding a policy to better protect migrants, refugees and asylum seekers, from advertising, which States that they are inferior to other groups of people, or shows contempt and disgust for him.

Zuckerberg also pointed out that sometimes Facebook does not remove content that violates policy of the social network, if the value to the public interest outweighs the risk of harm.

"Often a preview of what politicians say, is in the public interest, and similarly, news outlets will report on what policies we think people should be able to see it for themselves on our platforms. Soon we will begin to mark some content that we do not delete because it deserves attention, and people will be able to see when it happens" – he wrote.

Earlier, the national Association for the advancement of colored people (NAACP), the organization for the protection of civil rights, Color of Change, the human rights organization "anti-defamation League United States" (ADL) and other human rights activists urged the company to cease to advertise on Facebook in July, to protest due to the lack of regulation of such content.

On Friday, the company North Face has announced that it will not post to Facebook advertising because of "publications with hatred, violence, and racism" in the social network. Later, one of the largest U.S. Telecom operator Verizon Communications Inc has joined the boycott, refusing advertising in Facebook and Instagram. A similar statement was made by the company Unilever.
