Moving Content Between Obsidian & Social Media

Maybe this is a long shot and I’m the only one with this dilemma, but…we’ll see. A lot of what’s in my Obsidian vault is posts I’ve made on Facebook that I thought were worth saving. And much of what I post to Facebook comes from my notes. So I’m finding that I accidentally duplicate things when I’m going through my Facebook backups, and thinking I need to add some kind of “tag” for myself to the end of FB posts whose content came from my notes. That way when I go through my FB backups, I can immediately see that the content is already in Obsidian and not try to copy it back in.

Anyone else do something like this? Or have a similar solution?
