Actually, regarding the issues of listing and delisting on exchanges, I had a clearer answer during a meeting with the project team last month.

At least for Binance, it is quite difficult for them to come up with specific evaluation criteria for a whole bunch of projects.

Maintaining daily activity is actually not very costly when calculated, and the significance of Binance doing this is only to prompt some projects to focus more on data, which still does not benefit the community much.

This is also the purpose of my later research and investment; do not be deceived by the superficiality of the data.
