I hear you... (not that it was me - LOL)
Fortunately I'm only taking galleries from password submitters, and occasionally I send out an email pointing out broken links or the like (and skip the gallery until the next day), and I must say that over ½ of these webmasters reply and thank me, and many more at least fix their problems (though: I'm usually telling them something along the line of "other sites would blacklist for this straight away").
