honestly, i don’t see an issue with someone occasionally making a wrong ID. no one would ever grow as an identifier if they never tried to identify something new. that said, it would be good practice as an identifier to be relatively sure if they’re going to disagree with an existing ID, and to be responsive to discussion about any subsequent disagreements.
i’ve had folks come in and post disagreeing – and what i thought were obviously incorrect – IDs… and then would not respond after that. it’s annoying, but the good news is that this doesn’t happen a lot, and in most such cases, other identifiers will eventually come through with the right ID, and all will be good in the world again. you just have give the process some time to work sometimes…
i don’t think this is a great practice. there are some other threads that debate the practice. for example: https://forum.inaturalist.org/t/user-deleting-reposting-an-obs-to-i-presume-delete-a-corrective-id-alongside-a-comment-i-made/25844.
