I'm going to be honest with you.
This is an interesting concept, but I am seeing a bunch of problems with it, and not seeing a reason to use this over the existing moderator report system. In fact, I worry that people will use this instead of the report button, which is already a massive problem with #FediBlock, along with the trolling and harassment that goes on with that tag.
This seems to just be FediBlock with extra steps.
I also want to note, if this is only negative reports, you will have the drawback of some of the most popular and/or insightful people having the most reports, because that's who's getting that traffic. If you are really dead set on doing this, you really should have a system that lets people say a person is good, like that they are credible or make good content, so that those negative reports can be outweighed by people vouching for the person.
And once again, that's a problem with FediBlock too: we don't need more tools for shaming. We need more deescalation.
