But the same member of staff makes clear later in the same thread that there is no official iNat policy on excluding spectrograms. The views above appear to be personal ones:
I didn’t say it was an official position. It is my opinion. If we on staff thought this was a serious problem we would build tools to support or suppress these kinds of images, or at least include some kind of statement of policy in the FAQ or the Curator’s Guide. I would personally prefer that people not post these kinds of images as observation photos, but currently we don’t have an official position on them.
