I have many pose sets available at DAZ and Bbay, and have put many in the R'osity Free Stuff. Whether commercial or free, I consider poses to have NO restrictions on usage in images, as is, or modified. You can use any of my poses as you wish in renders. The only restriction is the re-distribution of the PZ2 file. That is mine. One obvious type of restriction would be to DL poses, modify somewhat, and post for re-sale. That is a no-no. I think some folx forget to indicate free usage when posting poses. And I think posting poses in Free areas is pointless if they cannot be used in personal or even commercial renders. They are so easy to weak, show from another angle. That's my posture on the issue...
