Hah, sorry, I read taxon name change and my brain shortened it to taxon change.
If the user added the names new to iNat and didn’t simply swap the default order, you can view the contributor name in the export linked here: https://forum.inaturalist.org/t/using-sql-to-query-inats-dwca-taxonomy-export/29377 You don’t need to use SQL necessarily, you can just open the corresponding spreadsheet, e.g. VernacularNames-english.csv for names in English, column H contributor.
