It seems incorrect that an ID that was made automatically/by the system due to a taxon change would count toward a user’s date that they were last active (displayed on their profile).
See also the related feature requests “Base “last active” date on public activity” and “Maintain original order of IDs after taxon changes”.
I was wondering why the last-active date on this profile https://www.inaturalist.org/people/bluebird101 did not match the dates of the latest identifications. So, maybe this bug has been fixed?
It could also have never been an issue in the first place - I am wondering if the user I looked at when I made this report just happened to not have any other public activity in a year other than taxon change IDs… but was logging into their account.
