How Knockoff Makes Takedown Cases Hold Up

Knockoff builds each case around one rule: a match only counts when your own product photo appears in the seller's listing gallery. Every confirmed match ships with an archived page, a timestamp, and a side-by-side comparison. You sign a Letter of Authorization once, which lets Knockoff file as your authorized agent on covered platforms — and you can revoke it at any time. Weak cases are never filed in your name. This matters most if you sell on marketplaces where a rejected or sloppy complaint can burn your credibility with the platform.

What counts as a confirmed match

The confirmation standard is narrow on purpose. Knockoff runs reverse image search across marketplaces, but a hit is only treated as a case when your photo is present in the seller's own gallery — not just a similar product, not a lookalike design, not a shared supplier photo.

The site's own example: your Walnut desk organizer listed at $68.00, found on Temu at $8.99, flagged as an "exact photo match, confirmed in the listing's own gallery."

That distinction is the difference between "this looks like my product" and "this is my photo." The first is an argument. The second is evidence a platform can act on.

The evidence package

Each match arrives with three things:

• Archived page — a preserved copy of the listing as it appeared, so the case doesn't evaporate if the seller edits or deletes it
• Timestamp — when the match was captured (the site shows scan times in UTC, e.g. "Last scan 09:41 UTC")
• Side-by-side — your original photo next to the seller's use of it, so the comparison is visible without interpretation

This is what "built to hold up" means in practice: the platform reviewer doesn't have to take your word for it or hunt down the original.

Who files, and under what authority

Two different paths apply depending on the platform:

The Amazon exception exists because that claim type has to come from the seller's own account. Everything else runs through the Letter of Authorization.

The Letter of Authorization is the legal footing. You sign it once. It authorizes Knockoff to act as your agent in filing takedowns. Two guardrails come with it:

1. You can revoke it at any time. If you stop working with them, the authority to file in your name stops too.
2. Weak cases are never filed in your name. A complaint filed under your identity that gets rejected reflects on your account, not theirs — so the confirmation standard above exists partly to protect that.

What happens after filing

Knockoff files the takedown, then chases the reply. That follow-up step matters because platforms frequently respond with a request for more information, a counter-notice from the seller, or silence. Filing is the easy half; getting to a removal is the part that needs someone watching the inbox.

Where this applies

The watched surfaces named on the site are Amazon, Temu, eBay, Etsy, AliExpress, Facebook, Instagram, and the open web — plus copycat storefronts, which are caught the day they go live. Setup is a Shopify store connection, described as about five minutes, with the first scan starting when you subscribe.

How to judge whether the evidence standard fits your situation

Ask yourself:

• Do your listings use your own original photography? The whole model rests on exact photo matches. If you sell generic stock-photo products, this confirmation method has little to grab onto.
• Can you produce the original image files? The side-by-side and the "your photo in their gallery" test both depend on you owning a verifiable original.
• Do you need filings under your own name, or through an agent? The Letter of Authorization route is what makes one-signature, ongoing filing possible. If you'd rather file everything yourself, you're paying for preparation and evidence rather than representation.
• Are your problem platforms covered? Check the list above against where your copies actually appear.

If the answer to the first two is yes and your copies show up on the covered marketplaces, the evidence standard is the reason to use it. If your copies are near-identical designs rather than your actual photos, this particular confirmation rule won't classify them as cases.
