I wonder what percentage of luxury goods are fake on Ebay? In my own experience, 100%. The sellers are not even apologetic - they take your return, issue a refund, and immediately relist the item.
They started efforts to curate that, but it's far from cleaning eBay 100%
What you're saying happens, more often than we wish it'd be the case.
That's why we never considered charging for our guides, even something as little as $1 → The point was to allow people to inform themselves about fakes, with as little friction as possible
That way, if we bump the % of people who get scammed by even a few negative points, we'd still be happy for a positive contribution
