This is hardly "inadvertently" revealing your location: (1) they've told you where they are (extra from the actual Tweets, not the photos) and (2) these places

This is hardly "inadvertently" revealing your location: (1) they've told you where they are (extra from the actual Tweets, not the photos) and (2) these places are all near well-known landscapes. I mean good job on taking the time to actually do it but I doubt this could be done for the vast majority of photos like this.
