I agree with others in this thread that such “identification farming” isn’t a problem provided that the observer has the required knowledge to make an identification. The problem comes when identifiers add confirming identifications of things they don’t really understand well or end up ghosting the platform after a few months. This can make it virtually impossible to correct incorrect identifications. I see this problem especially in central and South America where half a dozen identifiers or more will make an incorrect species level ID and be completely unresponsive to correction.
My recommendation: add confirming IDs if you are confident in your ID and you know what other species look like that in the area of the observation. Stop adding confirming IDs once it gets past four or so confirmed IDs to at least allow correction to happen in principle.
