The Algorithm Is Designed to Sell You Trash. Here’s Why.

You bought a cheap fan on sale. It arrived with a torn box, scratches on the plastic, and a faint smell of smoke. You thought about returning it, but the return shipping costs more than the fan itself. So you kept it. You got played.

This isn’t bad luck. It’s not a few sketchy sellers. It’s the system working exactly as designed. E-commerce platforms don’t just fail to stop bad merchants—their algorithms actively reward them for shipping you defective goods. Let me show you why.

In July, a viral post revealed that some sellers were cleaning up flood-damaged drinks and selling them as new on Chinese e-commerce platforms. The bottles showed signs of friction, but the caps were sealed. The brand was recognizable. The price was low. You’ve probably seen something like this yourself. A suspiciously cheap deal that feels too good to be true—but you click ‘buy’ anyway because the price is right.

Here’s the dirty secret nobody talks about: the friction of returning a cheap item is often higher than the value of the item itself. That’s not a bug—it’s a feature. Platforms know that most customers won’t fight for a refund on a $5 product. So merchants can ship junk, keep the money, and move on to the next sucker.

Compare this with buying the same drink in a physical store. The offline retailer has skin in the game. They charge a markup, so they make a profit legitimately. They also face real consequences: a bad review on the street, a lost customer, maybe even legal liability. Online, the merchant is a ghost. You can’t find their address. The platform’s complaint system is buried. Online, the merchant is a black box—and the platform is happy to keep it that way.

I’ve been there. I bought a bike computer that was clearly a ‘three-no’ product—no brand, no manufacturer, no production date. When I tried to report the seller on the platform, there was no option for ‘this is a counterfeit piece of garbage.’ I had to pay for return shipping myself. The platform never followed up. The merchant is still selling.

Even platform-owned stores aren’t safe. I bought toothpaste from a major e-commerce platform’s own store. It left residue on my electric toothbrush for months. I only realized when I switched brands. By then, I couldn’t prove it was defective. The platform didn’t care. When the cost of proof exceeds the cost of silence, the system wins.

Some people say, ‘Just don’t buy cheap online.’ But the problem isn’t the buyer. The problem is the architecture. E-commerce platforms show you the lowest price first. They optimize for conversion. They don’t optimize for quality. The merchant who sells a $10 fan for $8 is winning the algorithm—even if that fan is a fire hazard. Neutrality is death in content. In e-commerce, neutrality is just a polite term for negligence.

And here’s the twist: the very convenience that makes online shopping great—the vast selection, the price comparison, the geographic fairness—is the same weapon being used against you. The algorithm doesn’t know if a product is good. It only knows if it’s cheap. It doesn’t care if you return it. It only cares that you bought it. Your purchase is a signal to the algorithm that cheap junk works. And the algorithm will serve you more of it.

So what do we do? Stop blaming ourselves for ‘being too cheap.’ Start demanding that platforms change their incentive structure. Require return policies that don’t punish the buyer. Force platforms to verify merchant identities. Shame the ones that bury complaint buttons. If you bought something defective and kept it, you didn’t save money—you paid the platform to degrade your trust.

Next time you see a deal that’s too good to be true, remember: the algorithm isn’t your friend. It’s a machine designed to sell you trash. The only way to win is to refuse to play.
