Back a few years ago when I was building my SGI collection, I noticed an eBay consortium that pushed SGI prices to absurd levels. They'd even bump bids into legitimate SGI auctions, just to keep ANY of their focus items from selling too low. If they accidentally won one from a legit seller, amazingly, that account would have a non-payer negative feedback next month.
As I basically got the SGI items I wanted and kinda drifted from the scene, I don't know if it's still operating like that, or not. But this could be the start of a similar group for the Amiga. As mentioned, the trick would be proving it...
