Facebook is "working to restore" groups that was mistakenly removed due to "sabotage".
Earlier this week, a number of groups on the social network were targeted by an organisation known as Indonesian Reporting Commission (IReC), who had posted content "to sabotage legitimate, non-violating groups" on the site and get them closed down.
Now, a Facebook spokesperson has told The Verge that the social media platform is working to reinstate groups erroneously removed after content was "posted to sabotage legitimate, non-violating groups".
It was added that the company will also do what it can to "prevent this from happening again".
Meanwhile, WhatsApp - which is owned by Facebook - has this week advised users to update the app after they were hit by a cyber surveillance attack.
The messaging service issued a statement regarding the incident which they believe involved a "private company" affiliated with the government who managed to install spyware which could control devices via its phone calling function.
They said: "The attack has all the hallmarks of a private company reportedly that works with governments to deliver spyware that takes over the functions of mobile phone operating systems.
"We have briefed a number of human rights organizations to share the information we can and to work with them to notify civil society."
A new fix was issued in an update on Monday (13.05.19).
