@tiwane I know for sure of two additional ways people can select inactive taxa for IDs. One is when there is a taxon change and someone has opted out of having their content updated for them – which is presumably what happened with the most recent ID on this one:
The other is because inactive taxa show up in Suggestions.
EDIT:
Actually, I would argue the first scenario is a special case of the general situation where there is already an ID of an inactive taxon. So I think the fixes are:
- remove the Agree button from IDs of inactive taxa (regardless of how the initial inactive ID showed up)
- remove inactive taxa from Suggestions, or at least remove the ability to select them
