I do not know, and I didn't find much on their site other than a few good practices listed here: https://www.inaturalist.org/pages/community+guidelines

They do have a forum where etiquette questions come up, so that might be a good place to get a feel for it, e.g. https://forum.inaturalist.org/t/inat-posting-etiquette-questions/15317/5

The main thing seems to be honesty about your observations (if you're unsure of an ID, note that) and be available for comments and corrections on your posts.

Good luck!
