It also occurs to me that this can't be run by the instances using it, because they won't be able to see new instances to whitelist, which means you're going to need a few large servers to be the "Canary in the coal mine" for these instances. I feel like Tech Hub, with our somewhat squeamish block policies, could be a really useful server here, and I'd be happy to help maintain such a list.

What I think we need is some framework for how this list is put together and maintained, without too much overhead. We would need to account for the fact that such a list needs to be absolutely huge, and that while it should prioritize safety, there is an ethical obligation to get as many servers on it as possible.

As I told Jsit, it might be useful for someone to make this list now, just so we can see what it looks like.
