Yes, I’d suggest reading previous threads on spectrograms which include links to staff discouraging/asking users not to upload spectrograms. Examples:
https://forum.inaturalist.org/t/bat-observations-including-sound-and-spectrograms/39573
https://forum.inaturalist.org/t/bird-observations-with-only-merlin-screenshots/51185
But there are lots of others as well. They also discuss why many spectrograms aren’t particularly useful and encourage users to upload the actual audio files.
With regards to spectrograms, you may be interested in this feature request:

Some type of iNat-based process that generates spectrograms from audio via a standardized process which be much more useful than ad hoc posting of spectrograms.
