I am using common sense, honestly do not like care to have you imply otherwise.
iNaturalist is not encouraging killing in any form.
iNaturalist has no authority to do anything about illegal activities such as hunting violations ,or the destruction or theft of plants that are posted.
This is your judgement of another user’s experience. You are assuming the pride in killing as killing and never considered any other reason. You are assuming posting it was the only intent?
Was it a selfie or was there another person there that has little photography skill?
Are observers supposed to give reason on why they post observations of everything or only certain observations? “I posted this dead fish I caught for fun?” “ I posted these mushroom photos showing I proudly destroyed the mushroom to observe the structure of it”
