How to treat people who like to send screenshots of chat records to others?

I like to share screenshots of my chat records with others, which is also the characteristic of a person who likes to share in life. He will share it with you because he has talked about interesting topics with others.

I don't think he will share anything personal, but this kind of thing may have happened to everyone. Share chat records with others for reference. One more opinion is also good. I think it's a very common side of human nature. Nothing strange.
