@rndeon @pluralistic Author here, thanks so much for reading! I was just as blown away when I first dug into this and had the same reaction.
What is wild is that the logical fix for this, something called Server-to-Server (S2S) auctions like prebid server already exists. It offloads the compute and saves massive amounts of bandwidth. But because of certain data-matching limitations between servers, ad-tech prefers to hijack our browsers to keep revenue high.
To your point about messing with the bids, it is a brilliant thought! But currently, the client just collects the bids...the final clearing price is validated server-side by the primary ad server AFAIK. Spoofing the bid might just break the iframe or serve you a cheap fallback ad if they've built contingency measures(which I'm sure they have).
Dropping the requests entirely with an ad blocker is an incredibly effective and sane response! But I'm always open to hearing from smart people. Thank you for sharing 🙏✨
