What makes you say that? Couldn’t it be an immature adult?

> because they have a suspicion you might use AI

Was that the reason? From what I remember (which could definitely be incomplete information) the complaint was that they were clearly using AI while claiming no AI had been used, stole code from another project while claiming it was their own, refused to add credit when a PR for that was made, tried to claim a namespace on open-vsx…

At a certain point, that starts to look outright malicious. It’s one thing to not know “the rules” but be willing to fix your mistakes when they are pointed out. It’s an entirely different thing to lie, obfuscate, and double down on bad attitude.
