This is still malicious behavior. I will not name games that used such and similar "features" and were previously on the platform like steam, and itch.io. Ironically, they no longer exist, 'cause platforms removed them. You HAVE NOT permission to use this features, 'cause it's breaking many of terms, and breaking user's safety and privacy. Let me give an example: maybe your game not so destructive, but virus can infect it. So, what player gonna do at this moment? Right. He can't do anything, 'cause author of the game turned off permission to close it. I recommend to think again about it
