I just ID duplicates to the best of my ability and move on. If the observer is paying attention to their notifications at all, they’ll notice they posted the same photo twice.
Thanks for your input. What drove me to post this was a certain user posting several duplicates. I spent a bit of time going through their observations. This person is doing it purposefully, they’re definitely not mistakes. It’s blatantly obvious as if the person doesn’t care if anyone realizes they’re duplicates.
Flagging individual observations for review by iNat may be difficult. But what about flagging a user?
If a user gets flagged, iNat can review their observations. If it looks like they’re doing it purposefully iNat can message them directly with an ultimatum: remove your duplicates or explain why they aren’t duplicates. If they’re not removed and the user doesn’t attempt to explain why they aren’t duplicates iNat can close the account or restrict the user from posting more observations until the matter is resolved.
What I think hapens sometimes during CNC or other projects where schools have turned into a competition is that the observer may have posted a set of photos of their houseplants and all the flowers in their garden, delightedly finding themselves at the top of the class in the project page. Identifiers then go through and mark these as cultivated, and the student sees their rankings sink, their observations “disappearing”, so they post them again. And again. And again.
One way to find them all is right click and open a new tab with the observer’s observations, then sort by date observed.
This is relevant to a discussion in another thread right now on competitions and students, and this is the kind of thing that just can’t be filtered out in many cases unless someone has the guts to disqualify those observations. But, they are still in the iNat system and someone has to deal with them.
