How to detect if people remove your footerlink on a free custom style?

[chick]

You know I thought about this myself. Why not have it in just in the code source. I mean many forums run multiple hacks and cannot have every hack credit left in the footer or it would look pretty crowded and ugly, or better yet maybe a mod should be created as a credits page. I like that idea, credits page link could say for example: Coding Credits or something else.
