I will say that I have a burner account for OSINT data collection. Very useful.
So I originally gave it up as part of a "100 Days of Freedom from Facebook" challenge thing. I wrote on my status "If anyone wants to chat, here is my email address. Hit me up". After 55 days, I heard from no one. It occurred to me at that point that these people were acquaintances but that I really didn't care enough about what was going on to warrant the stress.
At the time, there was a small window where Facebook didn't just allow you to deactivate your account but actually delete it. So I downloaded all of my data (posts, pictures, comments, messages, etc) and deleted it.
