The first to notice a brand's counterfeit problem is often not the brand but the customer who bought the product. Lines such as "I got a fake", "this is not original", "the box is different" or "they sent an A-grade copy" are written in marketplace reviews, on social media and on complaint sites before they ever reach the brand. When these posts are monitored regularly, you see early which seller, in which channel and on which product is causing trouble. A single complaint does not prove that a product is fake, but it shows you where to look.
Where and how do customers write about fake products?
A customer who receives a fake writes in the nearest channel first. Each channel, and the language used in it, is different:
| Channel | Typical wording | Value of the signal |
|---|---|---|
| Marketplace product reviews | "Arrived fake", "not original", "smells different" | The seller and listing are known |
| Product questions section | "Is this original?", "does it come with an invoice?" | Doubt forms before the sale |
| Complaint sites | "I was sent a fake product", "they won't accept the return" | The seller name and date are often given |
| Social media posts | "Is this an A-grade copy?", "clearly a replica" | Images and the place of purchase are shared |
| Forums and community sites | "I bought a dupe", "where can I buy the original?" | Shows the general perception of a channel |
Some of these words describe counterfeiting directly: "fake", "imitation", "knock-off", "replica", "A-grade". On Turkish channels the same complaints appear as "sahte", "taklit", "çakma", "replika" and "A kalite". Others are indirect signs: "the box is different", "the barcode won't scan", "the serial number can't be verified", "the smell", "colour" or "texture is different", "it broke quickly". Searching only for the word "fake" misses most of the indirect complaints.
What information does a complaint carry?
A well-read complaint answers four questions:
- Which seller? A marketplace review or a complaint site entry often includes the seller name. If the seller is not on your authorized seller list, the signal gets stronger.
- Which channel? When complaints about the same product cluster on one marketplace or one social media store, the source of the problem narrows down.
- Which product and batch? A batch number, an expiry date or a packaging difference may be visible in the photo the customer shares.
- When? A rise in complaints after a certain date can point to a new seller or a new batch entering the market.
A single review rarely answers all of these. The picture becomes clear when complaints about the same seller or listing from several channels are brought together.
Does every complaint mean a fake product?
No. Customers also describe genuine products as fake. Common reasons include:
- The product moving to new packaging or a new formula.
- Differences in colour, smell or texture between production batches.
- Damage in shipping or unsuitable storage conditions.
- The product arriving in packaging made for a foreign market.
So a complaint is a starting point, not a verdict. Whether a product is fake is established by examining the product itself, with analysis where needed. A reply that blames the seller or the customer before the complaint is verified gives the brand a second reputation problem.
Which complaint should you look at first?
You cannot handle every complaint at the same speed. Priority follows this order:
- Health and safety risk. A suspected fake in food, cosmetics, medicines, food supplements, children's products or automotive spare parts always comes first.
- Repeat seller. If there are several complaints about the same seller, the listing and the store are recorded.
- Unauthorized channel. A complaint about a store that is not on the authorized seller list is a stronger signal than one about an authorized dealer.
- Reach. A social media post with images and high engagement spreads faster than a single review.
How should you reply to a complaint?
The first reply to a public complaint should be short and free of blame. Asking the customer for a photo of the product, the seller they bought from and the invoice starts the verification and shows other readers that the brand is dealing with it. Then point the customer to the official channels where the genuine product is sold.
The customer's rights lie against the seller. Under Law No. 6502 on Consumer Protection, the seller is liable for defective goods, and the consumer can choose among remedies such as returning the product, a replacement, a price reduction or free repair. The brand's reply is not meant to run that process for the customer, but to send the customer to the right place and add the suspicious seller to its own records.
How do you record complaints?
Complaint posts can be deleted and reviews can be edited. So an important complaint should be recorded the moment it is seen:
- The link to the post or review.
- The date and time.
- A screenshot of the post and, if there is one, of the listing.
- The seller name, the store link and the listing number.
- The product photo the customer shared.
This record later becomes the basis for a report to the marketplace or for your trademark attorney's assessment. How to capture a screenshot as evidence is covered in screenshot evidence for online trademark infringement, and how a marketplace report works in how to file a counterfeit complaint on a marketplace.
Public posts contain personal data too. Law No. 6698 on the Protection of Personal Data (KVKK) allows the processing of data made public by the data subject (Article 5(2)(d)). Such data is still subject to the general principles in Article 4, in particular processing for a specified, legitimate purpose and only to the extent relevant and limited to it. The right approach is to keep only the information needed for brand protection in the record and to explain this in your privacy notice.
How do you get from a complaint to an outcome?
Complaint monitoring is not a solution on its own; its real value is that it triggers the other steps:
- The seller named in the complaint is compared with the authorized seller list. We covered this distinction in unauthorized marketplace sellers.
- The seller's listings and its accounts in other channels are scanned.
- Where possible, the suspicious product is bought and examined.
- Depending on the result, a platform report is prepared or the matter is passed to the trademark attorney.
- After the report, you watch whether the same seller comes back with a new listing or account.
The route for impersonating accounts is covered in fake brand accounts on social media, and the damage fake products do to a brand in how counterfeit products harm your brand.
What does Authex do in this process?
Authex scans marketplaces, e-commerce sites, social media, ads, domains and app stores. Along with news, complaint, review and forum sources, the reputation feed includes content from the main social media platforms, and posts about fake and counterfeit products show up in this feed. Every finding is documented with the source link, a timestamp and, where possible, a screenshot, ranked by risk level and assigned to the relevant team.
Authex does not take legal action and does not remove listings or accounts. Notices are filed by the rights holder or its trademark attorney. Whether a product is fake is established conclusively only by examining the product itself.
