What I really want to understand out of this is:
for how many years a file uploaded on any board on endchan can reliably be accessible to anyone?

The file being accessible on a technical point of view alone, and not because it was removed manually by someone.
(assuming that file and its thread aren't slid into deletion, assuming the file isn't removed by either the board owner and site admins, assuming the file isn't deleted by a new board owner after the board is claimed, assuming the file is just left alone to take dust, how many years can the file survive by default site settings?)
