RE: Decentralized MMO
Yeah; despite what people say, it's incredibly obvious if a character is a real player or controlled by a bot. If a real person looks at a bot-controlled character, one can identify if it's a bot or not in just a few minutes with a very, very high precision.
And it doesn't even have relation to having bathroom breaks or stuff like that (as one can program a bot to emulate those), but it's that the bot always do things "perfectly". The bot doesn't missclick and opens the setting menu by mistake; the bot doesn't change the camera to a weird position; the bot doesn't stop for a few seconds randomly to check out the phone in real life or because the player yawned, etc.
