I was not having in mind birds. Birds for most of them are the easiest thing to ID and there are lots of IDers. And,actually, even the crappiest photo of an easily distinguishable bird is still identifiable. I was having in mind IDers for invertebrates,fungi and some more difficult groups of plants.If one does not upload a decent photo(s) of many of these, one cannot expect an ID. Sometimes, due to a photo quality the ID cannot go further than class or even phylum level. If the uploader is OK with that - then everything is fine. The worst cases are, of course,when the uploader provides genus or even species ID to their crappy image.
And yes, I agree that formula “get better picture next time” is annoying - the situations may vary. Much better is “picture quality does not allow further ID”.
