Obscuring all orchids is pointless. Only those threatened by collecting should be obscured. Many are under no threat of collecting, but heavily under threat of habitat transformation and aliens. There localities need to be known for them to be protected and not hidden. Furthermore, only those strongly threatened by collecting should be obscured: those with odd an casual collecting are better made known.
What I hear below worries me immensely. There seems to be a naivety about collectors. My experience is that most reputable societies have been "infiltrated", not necessarily by criminals, but at least by informants, and 'secret' information is not secret at all. Similarly, who controls who has access to projects and their curators and managers? It is trivial to set up a project on iNat and glean locality information: who is vetting project administrators and managers/curators to ensure that they are not part of the syndicates?
Ninety percent of the time the only people really inconvenienced by hiding information is those who need it in a hurry and daily to plan trips, monitoring and surveys. Anyone with a little savvy can crack most hidden data. Just the exif information on all these pictures allows easy data trawling: just look at it - file name (sequential), date original, date taken, date saved, not to mention sometimes coordinates, altitude, and lots of other information that can be used.
And then there are the pictures: habit and habitat shots often allow one to backtrack to the exact locality (in fact, are used to take repeat photographs from pictures over 100 years ago), other species in the picture offer clues, not to mention soils, water and other hints.
Clearly, no one here is thinking like a poacher! To really hide the locality, you need to not put on the observation in the first place.
It is interesting to parallel this debate with that on iSpot 5 years ago (orchids also featured prominently, and I swear some of those most vociferous were those I would trust the least). But on iSpot the major concern was the interval between posting and identification - although only 4 hours on average, iSpotters were paranoid that poachers would use that window period to extract all the data they wanted. Some iSpotters deliberated misidentified their plants as threatened species on posting just in case.
Hiding data completely is impossible. And it has costs. In the worst case scenario it gives the data to the poachers and prevents the monitors, law enforcers and conservation officials from knowing that their plants/animals have vanished under their noses. (of course, it could just have been the porcupines or alien boars)
