There’s a big difference between seeing escorts for casual sex vs saving their ad/gallery photos, let alone going through methodical processes to save them in better quality and making a considerable effort to unearth ones that are no longer there. The two behaviors combined are what make it creepy and borderline obsessive, which sets him apart from the ultra-organized hobbyist who just saves a single photo or two for reference/recordkeeping.Most people think that seeing a prostitute is "weird" and "creepy". So include yourself among those whose activities are weird and creepy.
To put it in perspective, imagine telling people that after you sleep with a civilian girl, you go sleuth her social media photos to save the ones that “do it for you”, and explore ways to dig up photos she previously took down.
OP’s Problem 1 literally describes the tedious process he’s willing to go through in order to save a higher quality version.As I explained above, it takes no more than a few keystrokes to screenshot a photo, edit it and save it. No "intensive lengths" are needed. Also you can't save "hi res" versions of photos that are low resolution to begin with. Most photos of girls on websites are low resolution.
OP’s Problem 2 refers to the lengths he’s willing to go in order to dig up photos that’ve been taken down. Sometimes the SP (especially debutantes) realizes a photo either has an identifying tattoo or can be recognized from her socials, sometimes an agency takes down a face photo they accidentally published instead of the blurred copy. Just take the L and move on.
The quickest solution to both problems would be to just ask the agency or the girl for the photo(s), but they don’t ask because it’s an awkward request. And it’s an awkward request because it’s creepy.
