A few points just off the top of my mind.
Don't you think this has quite a bit of an overlap with HW?
I didn't see you specifying your "guidelines" to downvotes. Will it just be on the whims of your appointed curators? Too much possibilities of abuse here imo.
I did not like the antiabuse project because the curators were anonymous.
Your downvote curators are going to be using their mains to DV where you will then follow up with your downvote trail?
Those are good questions! I think the answer for 1 is no because it would be my stake and not anything funded through the DHF. 2 it’s hard to have specific guidelines and I would think it would be easier to have a place where people can dispute the downvote. 3 I was thinking I would just use an account ticket and create another account. 🙂
