Those who invited me to play blockchain games and then ruthlessly scammed the players, what face do they have to invite me to play their new project?

Founders like this (and investors) should hide their faces and not come out to engage in community operations aimed at the C-end anymore. Although the success rate of new projects is relatively low, and it's not surprising to fail, it's still possible to see whether a project is a scam or not.

For new projects, find a spokesperson, quietly do the work behind the scenes, and let those willing to participate come forward. If it turns out successful, then they can show their face later to save some face.
