The only reason they deleted the static list of identified repositories was because of the negative PR of hitting HN. Although I have no affiliation with GitHub, I would imagine that no one with any resource allocation power is incentivized to take action to police public repos in general. The reality is that as soon as they start, it will become an arms race, and they will have to deal with false positives and the community headache that comes with that. They also have bigger fish to fry with the effect the influx of AI slop is having to their open source bread and butter. The two problems are not entirely disjoint, and I suspect solutions won't come until the problem gets much worse, and the agentic coding space stabilizes a bit more.
