Couldn't it be that the Romanian government (or someone who has an interest in this matter) is mass reporting these posts and users?

If I wanted to make someone shut up on Facebook; I'd write a bot that uses hundreds of fake Facebook accounts to report certain users. This would cause Facebook's automated systems to temporarily disable posting rights till they've had a chance to review the user in question. Eventually, Facebook's review teams would review the user and lift the block. But, usually there's a delay between reporting a user and Facebook 's review teams looking into it. Which is enough to shut up a user for a couple of hours.
