How do you decide where to draw the line between a knockoff brand and a legitimate new brand that just isn't well known yet?

Tried it on a few searches, the junk does get filtered out. One thing I'm not clear on: how do you tell a squatter from an honest new small brand? Both have no history and no reviews. Showing why a brand got flagged would help.

the community-report list is the part I'd want to stress test before trusting it - a crowdsourced override is great against false positives, but it's also exactly the surface a squatter would try to game by having their own listing mass-"reported" as legit from throwaway accounts. is there any friction on that path, like report weight tied to account age/history, or can a fresh brand get whitelisted purely on volume of reports

I like that it clearly marks what is assumed to be fake or poor copies, but that we can still see them.
Smart idea!

the linguistic scoring for pseudo-brand names is a neat idea but I'd worry about false positives - plenty of small legit brands from non-english-speaking founders end up with names that sound machine generated by accident. does the community-report list act as an override that can clear a brand the linguistic score flagged, or does a bad linguistic score cap how high a brand can rank even after being reported as legit

I installed it the other day and it works as advertised! Amazon is letting too much garbage into their store these days, and Knockoff helps sweep it back out.

Tested Knockoff and loved it! The UI is clean as well. I did not know something like this could exist, but I am glad you listed it here :)

Kind of funny to be at the stage where a product like this is needed for eCommerce in the first place but nevertheless essential to save time and help consumers avoid low quality products.

Great use case and example of a worthwhile Chrome Extension @shpigford

Ha, the name sells it. Curious how you're matching products — image similarity, or title/description matching?

The browser-extension angle makes a lot of sense here because the trust problem happens right inside the shopping workflow. One thing I’d be curious about: when the signal is not obvious, do you show users why a brand was filtered or flagged, or keep the decision mostly automatic?

Curious how Knockoff decides something is likely a knockoff on Amazon. Is it looking at seller history, review patterns, brand matching, listing text, or some mix of signals? The browser extension angle is interesting, but I’d want to understand how it avoids hiding legitimate third-party sellers or small brands that just don’t have much review history yet.

Love the concept! It's becoming increasingly difficult to tell which brands are legitimate on large marketplaces. Curious...how do you decide whether a brand gets a green check or a warning?

Nice work! 👏

@shpigford Knockoff is super cool. Being a parent, we usually shop for a lot of products on amazon and there are so many duplicate brands with fake reviews and fake ratings. Its extremely difficult to identify the true brands.

Just ran a quick search with knockoff and it works super well. Never disabling it. Kudos on the launch.

Super clean UI! I've been looking for a reliable Fakespot alternative and this seems perfect. Quick question: How often is the brand register refreshed? Rooting for you guys! 🚀
