Well, your last update on this was a few months ago and we don't know how this continued/ended.
But I was thinking about the IT guy that didn't response yet (at time of last update). If I were the IT guy (or any recipient of your email) I would NOT publish nor share your pic because that could bring me legal consequences: If your private photo, (that you explicitly asked me to not open and delete because was sent by "error"), appears later on internet or circulating in whataspp groups, then that could be a reason to get sued by you.
I don't know much of the legal stuff related to this kind of things (sharing private photos of others), but of course I wouldn't want to find out and learn the hard way.
I say this only to note that there could be alternate outcome to the "men sharing, commenting and masturbating to your pic" ;-)
