Method

Five steps. Bounded, documented, repeatable.

Cloaking defeats crawlers. It cannot defeat an actual paying customer, because the operator has to reveal the true money gate in order to take the money.

Step 01

Target

A priority list built from proactive targeting and a structured tip channel open to members, associations and the public. Targeting is driven by exposure rather than by notoriety: a merchant carried on a rail that also serves a hundred other shells is worth more to attribute than a single loud brand with nothing shared behind it.

Tips arrive through a structured intake so a claim can be triaged against what we can actually test. A tip that names an institution is not evidence and does not enter the collection queue as one. The list is re-ranked continuously.

Specimen — illustrative structure only. Not a finding.

Step 02

Onboard as a real customer

Native-language entry through the affiliate funnel, correct geography and device signature, plausible deposit history. The card rail is frequently not offered at all to traffic arriving from organic search; it appears for a customer who looks like the customer the operator paid to acquire. Auditors get served the decoy.

Same site. Same minute. Two different cashiers.

Step 03

Pay, capped and documented

A small real payment under a pre-set cap, set at the minimum value that reliably clears the operator's cashier. The payment exists to produce an authorisation record, not a position. No profit is taken from winnings.

Every transaction carries a full audit trail: the funnel it entered by, the timestamps, the cashier state at the moment of payment, and the authorisation and settlement records returned afterwards.

Step 04

Trace the settlement path

The acquiring BIN is the durable fact. A shell can change its name, its descriptor and its storefront overnight; changing the institution that acquires for it is slow, expensive and visible.

The descriptor as it lands is captured verbatim, and the orchestrator in the middle and the settlement route are reconstructed from the record. This is where a declared MCC is tested against the service actually delivered.

Before acquiring Transactions or Gaming Payment Transactions reflecting non-face-to-face gambling, an Acquirer must: Register the Merchant, Sponsored Merchant, or other entity with Mastercard … and Obtain and retain from each governmental licensing authority … a copy of its license to conduct the gambling activity for each applicable jurisdiction.

Correct coding triggers a registration that requires a licence. That is what the miscoding is for.

What we do not do

No intrusion. No scraping behind authentication. We do not induce a merchant to do anything it was not already doing. No payment above a pre-set cap. No profit taken from winnings. No contingency fees where the output must hold up as evidence.

We buy from the criminals you can't see.Then we tell you who banked them.
