This was a joke invented by r/anarchychess. I’d be amazed if it were real.

I remember when I first heard the rumours and I immediately thought of how sensitive one’s anal linings would be to perceive Morse code via a butt plug. Then pondered upon the Max possible bandwidth of buttplug-mediated information transfer. Finally, I thought about how to send back information via rythmic anal clenching.

Only then did I conclude that it’s probably easier to get better at chess.

A YouTuber tested it and confirmed it’s not that difficult to detect messages. That being said, they didn’t use Morse code but rather a simplified set of signals for move notation

It’s in the ankles, right? I guess even if it’s a different part of the body than the inside of one’s butt (a sensitive part of the body), makes it plausible that it’s also possible for communication (perhaps one-way—towards the plug wearer).

I’m assuming the accomplice would then be watching through some camera feed, right? That makes it at least plausible since there’s no need for kegels (to send information the other way).

Yeah, in terms of the other direction, the game would theoretically have an audience and livestream.
