Facebook is under global pressure to clamp down on hate speech, violent threats or deliberately misleading information on their platform -- with efforts showing varying degrees of success.
Dozens of users in Myanmar reported being temporarily barred from the site recently after posting the controversial term kalar, which is frequently used as an insult for the country's embattled Muslim minority.
Some users said they were even blocked after writing other words that include the same sound in the Burmese alphabet, highlighting the difficulties Facebook has monitoring millions of posts in multiple languages.
"It is ridiculous," he said. "I became a victim of it myself when I wrote: 'Facebook is deleting the posts that include the word kalar'."

Yarzar Soe-Oo said he was barred on Friday after posting a jokey quip about eating Indian bean soup ("kalar pal hin") while sitting in a chair ("kalar htaing").
Facebook did not reply to emailed requests for comment while a spokesman for the Myanmar government said it had not pushed for a ban.
Over the years it has also been turned into a derogatory slur by Buddhist nationalists against Muslims.
Two angry Facebook users have responded to the apparent ban by creating an event called "We own Kalar" in protest.
By early afternoon some 1,400 people had said they were interested in attending the gathering, scheduled for Wednesday in Yangon.
"Even though no action is taken against fake accounts which share hate speech and spew abuse... Action is taken over (words we use every day)," said the organisers.
The push comes as Myanmar's government has been seeking to clamp down on hate speech after a spike in anti-Muslim actions by Buddhist hardliners.
