Facebook has helped to introduce thousands of members of Isis to one another through it’s “suggested friends” feature, it has been reported.
The social media company has been accused of aiding of extremists and allowing them to develop wider networks.
Algothirims used by Facebook suggest users connect if they share common interests.
Researchers, who analysed the Facebook activity of one thousand Isis supports from 96 countries, found they were often introduced to each other through this feature.
Robert Postings, one of the researchers, said after he clicked on non-extremist news pages about Islamic uprisings, he received multiple friend suggestions from extremists.
"Facebook, in their desire to connect as many people as possible have inadvertently created a system which helps connect extremists and terrorists,” Mr Postings told The Telegraph.
“Over a period of six months the [US based user] went from having no clear religion to becoming a radicalised Muslim supporting Isil.”
The study also looked at the steps being taken by Facebook to clamp down on extremist material that is spread on its site.
Of the 1,000 accounts that it looked at, in a period of six months less than half were suspended by the social media giant.
Gregory Waters, one of the authors of the report, said Facebook had become a place where Isis supporting networks were able to exist.
"This project has laid bare Facebook's inability or unwillingness to efficiently address extremist content on their site,” Mr Waters said.
