Checking a site is not claiming it: anyone can check any site, and its owner alone can claim, correct or hide it.

This is not a certification: it is what our crawler read on mermail.app's own site and doors on 2026-10-07, scored by the published rules. Nobody can pay for a score or a place.

Evidence: declared — the business's own site or door says so; we have not tried it.
