That's fair tbh, I agree there is an unmet need for something like this, so no arguments there. It is only fair that the users should have at least an equal say

That's fair tbh, I agree there is an unmet need for something like this, so no arguments there. It is only fair that the users should have at least an equal say in keeping companies off of their search results. The search engines are making the choices for you because you're the product, not the customer. The implementation details take time to get right. And getting this far in an afternoon as a non-developer is pretty respectable. If you want to have the most reach / impact with something like this though, it will take consistent, sustained effort over a long period of time, and it will be a thankless job, at least for awhile.
