No, not the ones here. But
this article points out two eye-opening examples (from the Sierra Club and Costco, two well-known "progressive" organizations, no less) of contests whose terms are so outrageously slanted against photographers as to constitute a form of fine-print trickery. How bad? Well, how about a clause where entering the contest constitutes transferring all
ownership rights to the image to the company running the contest? Or one where not only is the organization granted a free license to use your photo, and even assign that license to anyone else it wants, but where
you, the photographer, agree to pay all legal expenses if, for whatever reason, the organization gets sued by anyone else on account of your photo? (Note that, in each case, you have to give up those rights just for entering the contest, whether or not your entry goes on to win anything.)
Just a reminder: when entering a photo contest, read the fine print
very carefully. Lots of contests contain terms that are pretty much a free "rights-grab" which could leave the photographer with having lost control of his or her image for nothing in return. When in doubt, don't enter!
