I would say it’s not necessary if the post is public. I would consider it if it was clear the conversation wasn’t meant to go viral, or if I suspected the person wouldn’t want the extra attention on the platform (for example it’s funny but it’s embarrassing, or maybe I know they don’t fully understand the privacy settings of a post like it happens with some elderly people). It’s a grey area for sure
Play games, watch movies, spend time with family and split whatever money I got left with them.
