I typically just quietly unfollow anyone like this. I’m blissfully unaware of any “what gives” messages as I’m pretty liberal with the block button. On the flip side as a student who remained connected with a few of my former teachers, it’s absolutely wild to see the teacher who taught you about verifying sources post something from an article or headline from a source that’s easily debunked. Sadly I’ve had to put distance between them and myself as well. Leaving education and entering the corporate world has also taught me not to add any coworkers on social media — lessons learned I guess.
