Just a mention that sometimes the OP errs by typing in their choice of ID and selects a homonym instead from the subsequent dropdown menu. For instance there is a plant genus Oligochaeta and annelid subclass Oligochaeta
I have also noticed this happen to seasoned identifiers of insects selecting a conflicting homonym.
It is a very easy and honest error to make. My approach is to make a polite comment directed to that particular identifier with @OPusername. I will also politely PM the seasoned identifier because often they get a plethora of notifications and may overlook your mention.
Even if you are not confident yourself to add an ID, your comment may help a subsequent identifier balance the observation in a more positive direction.
You may also notice that by checking the OP profile that they are no longer active on iNaturalist. I do this check on older observations where the OP has very few observations.
