Provenance

A welcome offer read on a bookmaker's own promotions page and a welcome offer that four affiliate sites agree on while the bookmaker publishes nothing are not the same claim, and they are not the same claim about a real company either. The first is the operator speaking. The second is an industry repeating itself, and in this market the repetition is measurable: several figures in wide circulation trace back to one source wearing four hats.

So every field on every entry here carries where it came from. Read on the operator's own surface, agreed by several third parties, carried by exactly one, or checked and positively absent. The fourth of those is the one most often lost: a promotions page that was reachable and had no first deposit offer on it is a finding, and turning it into a blank cell throws away the work.

The same discipline applies to figures this publication holds and will not print. Where a record names a number as unsupportable, the index says a number is held and not printed rather than quietly rendering it, because the alternative is repeating a claim in a company's name.
