Twitter has been filtering religion-related hate speech on its platform since Tuesday, attempting to broaden its fight against malicious messages posted on the social network.

In a document published on the company's blog, Twitter said it would remove tweets that "dehumanize people on the basis of their religion," when these messages were reported to him.

The group said tweets published before Tuesday and reported will also be deleted, but will not be suspended account, having been published before the hardening of these rules.

Twitter, however, does not specify in his post blog if the tweets published after the tightening of the rules will be accompanied by a suspension of the account at the origin of the offending message.

To illustrate his decision, the social network takes examples of what he considers dehumanizing statements against a religion, such as "disgusting" or "dirty animals".

Twitter is engaged in a broader movement to combat hate speech on its platform. The group led by Jack Dorsey recently announced measures against politicians' messages inciting violence or hatred.

Most observers saw this as a targeted measure against Donald Trump's frantic tweets.

The social network also has clear rules for all tweets specifically calling for violence against an individual or community, glorifying terrorism or harassing a particular person.

Twitter is, like Facebook and other social networks, regularly accused of not doing enough to combat hate speech. The group is struggling to reconcile this objective with the preservation of the open nature of platforms of this type.

It is in this context that the US president, very critical of Twitter and Facebook, which he often accuses of leaning left, must hold Thursday a "summit on social networks" in the White House, without the main stakeholders but with the most critical conservatives of Silicon Valley.
