What is the mentality of people who often delete QQ space?

I speak in QQ space, just to make my friends notice my dynamics, attract their attention, and also to make interactive comments or praise with them. Sometimes the idea is to brush the sense of existence among friends and find comfort and compensation in my heart. I can send it whenever I want, and I have hardly deleted it. I think people who often delete space to talk should be too many people in QQ, afraid of being seen by others, insecure, a kind of self-protection, so it is very contradictory.
