I do think it would be good to have a system for identifying harmful stuff. It would be a nice workaround that would work today and I would definitely adopt it at https://njump.me/ because we keep getting reports from Cloudflare. I tried some things but they didn't work very well, so if you know how to do it I'm interested.

However the long-term solution is paid relays, community relays, relays that only give access to friends of friends of friends, that kind of stuff.
