Taxon history change credits "iNaturalist"

what’s up with this case where iNaturalist is listed as being the user to have deleted a common name?

What we think is going on here is that the user ID for that change is null - perhaps they deleted their account since making the change. And the system uses “iNaturalist” for these situations, like when it makes a No vote for Organism is wild in the DQA. We should use something like “deleted user” here instead.
