Facebook this week removed 168 Facebook accounts, 28 pages and eight Instagram accounts for engaging in "coordinated inauthentic behavior" targeting people in Moldova, Facebook's head of cyber security policy wrote in a blogpost Friday.
Nathaniel Gleicher said the activity originated in Moldova and used a combination of fake accounts and some authentic accounts to mislead others about their identities and intentions. It comes as Moldova prepares to hold parliamentary elections on February 24.

A manual review of the network found that some of the activity was linked to employees of the Moldovan government.
"Given the upcoming elections in Moldova, we wanted to let people know about the action we've taken and the facts as we know them today," Gleicher said.
Gleicher said a tip from a local civil society organization played an essential role in the investigation.
He said the page admins and account owners mostly posted about local news and political issues, such as required Russian or English language education and reunification with Romania.
