@Shadow94321 The only way to permanently fix this is to remove the global chat. No algorithm they write will trap the bad guys 100% of the time and not also punish innocent people.
The only way to fix this is to take a risk yourself. You could confront the person in global, but you risk 1) misunderstanding what is going on, and 2) you could get banned from the global chat from the very predator or bully you are trying to stop.
The best thing to do in global chat is not go in. If you feel you must then consider suggesting that people should not be revealing their age in the global chat, because they could easily be exploited.
