You know what annoys me? People who set up a poorly-designed, slapdash fan site for some famous person on GeoCities or Tripod or some other such free hosting service, but then decide to render all of the photos on the site useless -- even for perusal, much less for copying for my own purposes -- by using Photoshop or whatever to put a big "stamp" with the site's GeoCities or Tripod URL right over the head of the famous person in question. This practice is idiotic, and I see it far too often.
