Facebook management and employees probably aren't even aware. They outsource this censorship.
It's akin to SDS outsourcing board moderation to an accountant who hired teenagers at minimum wage to review every post and decide in 60 seconds whether or not a poster should be blocked for that post without knowing anything about the person, board, or topic of discussion.
Basically, it's not a grand conspiracy by Facebook. It's just a *****-ass moderating scheme.
