Another interesting way to get loads of free
pr0n and thereby rob
porn sites of revenue is to put together a set of scripts that suck all the binaries out of
alt.binaries.pictures.erotica, reassemble and
resize them and put them into a handy, easy to view porn site.
This is actually what we did at my last place of employment to create our own pr0n site. Of course, being the smart geeks that we were, we made it nigh on impossible for you to rip us off with wget. We had a perl script that fetched the image based on a rather nifty algorithm which meant that you couldn't simply download an entire directory by guessing filenames.
Of course, we didn't bombard people with banners, either so we didn't suck.
As I recall, we used a combination of suck for fetching news articles, perl for processing and general coolness and imagemagik to do thumbnails and full-sized pix.
It was quite a cool setup, actually.
