Today’s business idea: Develop a database of adult images and films to help sites ensure regulatory compliance. Key each item by its md5 sum, map to subjects and store subjects’ dates of birth. Hand out free accounts to eager young men in exchange for indexing. Use redundancy, incentives and penalities to ensure quality indexing. Write a perl script that crawls the site operator’s filesystem, computes the md5 sums, and calls Web APIs to query your database. Sell the perl script for a one-time fee and charge monthly for access to the continually updated database. Bottom line: a bunch of guys get free porn, site operators stay out of jail, you make a fortune. Oh, and don’t forget to cut me in on the profits 🙂 See also: MusicBrainz
