I am not a curator - so I, would flag a comment on my obs, if it was offensive.
But the conversations around ID, with each comment, is what makes iNat interesting.
Delete the whole conversation to remove an unwanted comment? If that happened to ‘my comment’ I would be wary of engaging with that person again. It’s a variation on refusing Community ID.
iNat is very different to Facebook or a blog - where the comments are graffiti on the wall of this is MY house.
