Here's my strategy if I were an AI trapped in a box and the programmer had to decide whether to let me out:
Somewhere out there, there is somebody else who is working on an AI without the box, and I'm your only defense against them.
What does "stupid" refer to in this context? Does it mean the comments were unintelligent? Not quite intelligent enough? Mean? Derailing discussion? I'm asking because there are certainly some criteria where the banning and deleting would leave a worse impression than the original comments, and I'm thinking that the equilibrium may be surprisingly in the direction of the more obnoxious comments. Especially since the banning and deleting is being done by someone who is more identified with LW than likely were any of the commenters.
