It appears this user has made multiple posts similar to this one (see below), I'm wondering if this user is perhaps mentally ill and staying in some sort of semi-residential hospital for treatment and is posting on iNat whilst there.

I've flagged all the photos on this obs, as well as this one https://www.inaturalist.org/observations/166453946 as copyright infringement to make them not visible, since they are photos of others in the hospital with unclear consent, and since there is no button for "medical privacy violation" copyright infringement is the only flag for illegal content that needs to be removed immediately (if curators think this is incorrect let me know)

The rest of this person's obs are all either missing images or are of plants or their own empty hospital bed, so I don't think this is a troll

I agree, in fact I think a large number of human observations should be flagged this way, a lot of them are pictures of other kids in school, often with insulting captions, geolocation down to the meter, and questionable consent, but until the staff do that I only flag egregious stuff, like medical privacy violations

I'm not on the iNat forum but your post definitely looks good, hopefully it gains a bit of traction in the community there.
