Dear Microstock Agency:
It has come to my attention that in some of the photographs I have taken of myself, I did not give myself permission to use myself for commercial purposes. While I did give myself permission for some of the images and have signed model releases for myself to take pictures of myself and sell pictures of myself for myself's personal gain, I didn't give myself permission for other images and myself has uploaded those pictures of myself without my permission.
In the future, Unless I give myself permission for each image I take of myself I don't want it assumed that I gave myself my permission to use the likeness of myself in my portfolio. I appreciate your prompt attention to this aggregious error and please give all of your lawyers a raise and take it out of my earnings.
(Note: I didn't give myself permission to include that last sentence.)
