I own a few 100k+ pages on Facebook. On one of my pages, I've received the following messages 4 times over the past 2 days. The message reads "Hey ***Name of My Page***, I think this content is my intellectual property, and it can't be used without my permission. Could you please message me back about this or take it down?" All 4 messages were exactly the same and each of them were regarding different videos/link posts shared on my page and were sent from different FB accounts all of which seemed to belong to senior citizens (looks like 60+ years old judging from the profile pictures). The FB profiles look legitimate with real friends and interaction. I wonder if these accounts are hacked. I can't figure out why someone would send such messages to my page. Am I missing something here.
