Send it
Use Suggest a place: the place’s name, where it is, and a link to the operator’s page that shows the right fact; say what is wrong in the note. Or email hello@jukkablomberg.com. A directory listing helps us look, but is never the source.
What happens next
We open the page you send. If it shows the fact, the record is corrected at the next research run, and its page shows the new reading with the date we checked it. If it does not, the record stays as it is.
Where it is logged
Every change to the register is listed in the changelog; released history is never rewritten, and a correction gets its own entry. A month already frozen is never edited: a corrected status shows up in the next snapshot of the hash-chained status history.
