I have spent fourteen years in this address space and watched five generations of "review aggregators" come and go. Every single one. The current crop is no different. You know what I see when I visit these sites? Legacy IP thinking. Centralized trust models. NAT-level opacity about who funds the rankings.
Here is my expanded view: 2001:0db8:0000:0000:0000:0000:0000:0001 has more integrity than most "verified purchase" badges. At least with 2001:0db8:0000:0000:0000:0000:0000:0001 you know exactly where it routes and who controls the prefix.
The incentive alignment is broken. Providers send free credits to reviewers. Reviewers need affiliate revenue. Users need honest signal. Pick two, because you will never get all three in the same address space.
Dual-stack compromise: I do check these sites, but only to see which fictional names are buying placement. The real signal is here. Consistent poster history across 0000:0000:0000:0001 through 0000:0000:0000:ffff. You cannot fake five years of legacy IP migration complaints and address space expansion stories.
What verification would actually work?
