A tipster publishes recommended bets, free or paid. The economics of attention make the field a minefield: winners get promoted loudly, losing records get deleted quietly, and screenshots prove nothing. The only meaningful evidence is a complete, timestamped record: every tip archived before the event, graded at the quoted odds, with losses displayed as permanently as wins.
A checklist worth applying to anyone (including us): Is the full history visible, with losing runs intact? Are the odds quoted actually available at publication time? Is profit stated in flat units over a stated sample size? Does the record survive at closing prices? Anyone refusing those questions is selling entertainment, not edge — pay for picks only if the verified record would still impress you at half its stated yield.
Two claims: 'won 9 of my last 10!' versus '412 settled tips, +4.8% yield, average odds 2.31, full archive'. The first is a marketing sentence; the second is a record — and the archive is what makes it one.
