Exactly! This is the problem we are facing and i'm sure other's would be facing as well while hosting a gamebot in their chat.
The problem is when we were playing gamebot, a random user Private Chat the gamebot say !stop or any other command which makes the gamebot leave in midway.
Earlier, there was a system when the gamebot used to PM us in main saying , "Sorry, you require power to control the bot". But in the current situation, the gamebot just goes offline.
So, while i was hosting, a user kept coming and tried saying the command in pc of gamebot and making it leave again and again, leading to disruption..
