Duplicate obervations

How about introducing an option which can be useful for identifying duplicates uploads? same photos uploaded by user with the help of this option curators can mark that foto is uploaded multiple time for the same taxon and latest upload can be marked as duplicate and it won’t be counted in his list


for example here
https://www.inaturalist.org/observations/55724066 uploaded by user on Aug 8, 2020 · 12:33 AM IST
and the same Photo again uploaded by user on Aug 13, 2020 · 1:54 PM IST

I’d mark them both as date incorrect until one will be deleted, they’re uploaded for completely different dates and years.
UPD. Exit is present on only one version of the pic, so I marked the second date/observation as incorrect.

It is mentioned in the past.

I only know that the one Wikimedia is using to prevent duplicates is working nice.

If you’d like to request a feature, please submit to the feature request category.
As it turns out, there is already an existing request to check for duplicate images, so I’m going to close this thread to focus discussion there.
