I have released originals for certain purposes with a strict license agreement. Deviation from that license agreement carries built-in $1000 penalties. I only release images to people I know will abide by the agreement. The aggravation of court isn't really worth it, and would just make me mad I released them in the first place.
There's a couple of different revenue streams I haven't tapped into yet that will be much more effective than digital sales. Now that the season is coming to a close, I'll be able to publish 2011 and put it to bed, and finally focus on revamping everything for 2012.

And the long-awaited autocross photos will finally see the light of day.
