If I’m understanding correctly, and please correct me if I’m wrong @sandboa, the subject of this post is regarding people who are already aware of the current taxonomy on iNat, have already discussed the taxonomy with staff, but continue to add IDs that run against the established taxonomic framework. And are already aware of the policy mentioned above. So, what to do? (With an issue this pervasive, I believe it needs to be addressed by staff, not through the flagging/curation system.)
As far as generally talking about existing or desired deviations, those discussions usually take place on taxon flags. For larger discussions that relate to many different taxa or general policies, trying to hold discussions in the working group projects doesn’t work because only project admins can create new journal posts.
