Why Skeptik exists
We don't think everyone's lying. We just think the internet gives strangers a little too much credit.
Every day, people spend hundreds or thousands of dollars based on a few photos, a description, and a feedback score. Sometimes that's enough. Sometimes it isn't.
That's where Skeptik comes in. We don't try to prove a listing is legitimate. That's almost impossible. Instead, we ask a simpler question:
Would an experienced buyer spend their own money here?
That single question drives everything Skeptik does. Seller history. Photos. Buyer feedback. Pricing. Marketplace patterns. Every signal exists for one reason: to understand whether we'd feel comfortable buying it ourselves.
Experience matters. An experienced buyer doesn't just notice red flags. They notice combinations. A stock photo from a large retailer is probably normal. The same stock photo from a brand-new seller asking thousands of dollars makes us pause. Context matters. Always has.
Skeptik isn't replacing your judgment. It's sharing ours. The goal isn't to tell you what to buy. It's to help you notice what experienced buyers notice before spending your money.
Skeptik was inspired by two decades of buying, selling, and occasionally getting burned. We figured it was time those lessons became useful to someone besides us.
