There doesn’t appear to be any option to simply undo or delete photos based on upload date, and the website chokes when I try and delete a selection of ~5,000 photos. The photos span a wide range of dates and are consequently mixed with my own photos in the standard view.
Edit: Alright folks, it took a while but I got it cleaned up without having to nuke my account or anything. In case anyone else finds themselves in my situation… You can get to a page that sorts by upload date if you click “View uploaded photos” in the Google Photos desktop app. From there I selected and deleted 1,499 photos at a time, because the website would choke on 1,500+ for whatever reason. Thanks, everyone. The nightmare is over…
