When it comes to AI usage, I'm very much an advocate of it being unethical in basically any way. Obviously, if you even use most things on the internet, it does the damage without your intention, but there's a difference, to me, between Googling something and the AI automatically sending you a result and you kind of ignoring it and looking for an actual source/just clicking on the source cited by the AI, and going out of your way to use AI to generate something to aid you/search for things.
If you're using AI, you're actively partaking in the negative usage of AI. It's made even worse when that usage of AI is explicitly banned in the thing you're using it for. It would be like if you commissioned a painting from someone who says they never use AI, but then they used the AI search to work out how to mix a specific colour. Sure, it might seem minor, but it goes against what was asked by the commissioner.
I believe I've been messaged by one of your teammates about this on Bluesky already; they asked if they could remove any AI-assisted code and redo it and then be let back in the jam. I've allowed this, since it was seemingly a choice made against the team's wishes. I appreciate you coming here to ask and to learn and I hope you take these words on board, because other jam hosts might not give a second chance so easily. Even if, after all of this, you still don't believe you did anything wrong, I would only ask that you apologise to your team.
