1. You try to ban low quality vibe-coded projects, but try to not ban high quality projects that made use of AI. The goal is to send a message on what you deem acceptable. 2. Anyone creating what you deem a low quality vibe-coded project sees their project as belong to the second kind of project and therefore insists that their project is allowed. So how do you make sure what category a project belongs to? You might use scripts to identify classic trades of vibe-coded projects, look at the users history, etc. None of that is going to be bulletproof though and it is a lot of work. 3. You stop trying to enforce this rule as it is a "fight" you can't win and dealing with this takes more effort than dealing with the issues the low quality vibe-coded projects caused in the first place.
We ended up settling on restricting new projects instead as the majority of projects that fall into the first category don't last long. So step 4 would be to introduce some other kind of proxy for this kind of project that can actually be enforced.
