Hate speech on Facebook has been an incendiary issue. The latest action is unlikely to be received quietly. Nor is it likely to quell the problem completely.
It banned the Buddhist nationalist movement Ma Ba Tha from its platform, as well as a pair of prominent monks known for stoking hatred towards the Rohingya.
“They are not allowed a presence on Facebook, and we will remove any accounts and content which support, praise or represent these individuals or organisations,” said content policy manager Mr David Caragliano.
Extremist monks Parmaukkha and Thuseitta join their fellow firebrand clergyman Wirathu on the blacklist, after he was banned in January.
Activists have criticised the platform for responding too slowly to reports of malicious posts, with some content being shared by users for more than 48 hours before being removed.
Examples include calls for the killing of a Muslim journalist and posts last September saying Buddhists and Muslims were each preparing attacks against the other.
