Long time ago I had an extension for my browser that would "pause" every social media comment I made and do analysis to see if I was acting like a dick. Maybe I should get it working again.
It all started when I found some website where you'd give it your Reddit account, and it'd do a bunch of processing and produce a report about how much you swore, if you had net favorability or not with up/down votes, sentiment analysis to see if you were coming from a place of friendship, etc. It really drove my behavior in a more positive direction.
I'm a kind, not just nice, person IRL. But the Internet turns humans into text, and I was taught as a child to engage harshly and critically with all text. That is to say, I had good English lit teachers.
