From past experience, it's better to stop keeping up with friends that you don't get anymore remember them as they were, and say hi when you run into them IRL than it is to *constantly* absorb information that makes you view them as terrible, justified or no. Unfollowing: Better for all parties.
@bradamant I fear that online personas are representative of inner dialogue, but in a way, if they are decent every time they interact with you IRL, does it matter?
Wait, I guess it does, but mostly for matters of character and personal trust, not sharing experiences.
