What's the best way to respond to a mean post on your social media? Do you stoop to that person's level? Or is it best to just delete the comment and snooze or delete/block the person?

Whenever I post something personal about myself, I have this one acquaintance who will go out of their way to post something very snarky in response. I really want to confront this person about their behavior. Because I don't know why they are being so mean.

Part of me feels like it would be a waste of time to confront them b/c they clearly don't like me (per their snarky posts), so confronting them wouldn't change their behavior.

Anyone deal with this type of behavior? We're not great friends, just acquaintances.
