Auction Houses Urged to Unite + Why Some Comps Shouldn’t Count + Private Sales Under the Microscope

We dig into Auburn’s big idea: auction houses collaborating on a shared shill-bidder list to protect buyers and legit sellers. Chris explains how some marketplaces already purge unpaid sales from data, and why tougher KYC/AML-style identity checks could raise the bar. We also break down private sale transparency, when a headline price is really marketing spend, and how to contextualize comps so you don’t get wrecked by bad data. Topics: Cross-auction shill blacklist & real penalties Fanatics sending unpaid-item removals; why more should do it KYC / AML-style identity verification for bidders—practical or pipe dream? Private sales: docs, names, paper trails, and fraud risk Comp literacy: float, intent, rarity, and why not all sales are equal PSA Offers, vault deals & what should count as a comp Disclaimer: Nothing here is financial or legal advice. Verify policies with each marketplace. If you found this useful, like, subscribe, and drop your thoughts on shill enforcement & KYC below. Learn more about your ad choices.
