Identifying who is behind an anonymous seller

A storefront with no name, a burner email, a company registered to a flat in another country. It looks like a dead end. It usually is not. Most "anonymous" operators leave a trail in three places, and the law gives you a way to pull on each of them. Here is how a careful firm actually does it, and where it stops.

Start with what is already public

Before anyone goes near a court, there is a surprising amount sitting in the open. The same profile photo reused on another account. A phone number that appears on an old listing. A logo registered as a trade mark in someone's real name. A domain whose registration details leaked before privacy protection was switched on. This is open-source intelligence: patient, lawful gathering of scattered public information until the pieces point at a person. Often it is enough on its own.

Follow the money and the parcel

A product still has to be paid for and posted. A carefully run test purchase, bought and documented to a standard that would stand up later, can reveal a payment account, a return address, a dispatch label, or a supplier's details. Each of those is a thread that ties a faceless account to a real name. Done properly, the seller never realises it was anything other than an ordinary order.

When the trail runs out, the court can compel disclosure

This is the tool most people do not know exists: a Norwich Pharmacal order. It is a court order that forces an innocent third party, a marketplace, a bank, a payment processor, a web host, to hand over what it knows about a wrongdoer using its service. The platform that has been shielding the seller can be required to disclose the name, address, bank details and contact information behind the account. You can also start a claim against "persons unknown" and unmask them as it progresses, so the absence of a name is not the obstacle it appears to be.

Where we draw the line, and why it matters to you

There is a hard line between lawful investigation and the things that make for dramatic television: no hacking, no pretexting people into handing over data, no deception that a court would frown on. We stay the right side of it, and not only for ethical reasons. Evidence gathered improperly gets thrown out, and a tainted investigation can sink an otherwise winnable case. The discipline is the point. It is what lets you actually use what we find.
