evidence A → F — We graded El Capo A on months of clean operation, and they were a paying headline sponsor -- which is exactly what a patient exit-scam invests in earning. The A was honest on the evidence then; this reversal is honest on the evidence now. Trigger: a ~$45,400 non-delivery on order KR-71B69B10 (2026-09-07). El Capo's partner API issued the deposit address, their own key swept the BTC on-chain, they delivered no XMR, then denied the order existed and stalled past the 24h ultimatum. Grade dropped A -> F; the headline sponsorship has been terminated. Grades are not for sale and a paying sponsor gets no shield -- that is the entire point of the firewall. Beyond the sponsorship, we also earned affiliate revenue-share routing orders to El Capo; we are ending that routing and warning users away, forfeiting that income. Neither our grades nor our routing are for sale -- we are downgrading a service we were paid by and profited from, against our own financial interest, because it stopped paying users.
