I think people make 2257 a lot more difficult than it really is.

1. Do you show naked people on your website partcipating in sexually explicit conduct?
2. You need to comply with 2257.

Like Greenguy said, obviously a member is not content on your website, you are only responsible for the people that perform on cam.

Now, I guess it's possible that your members could be using cams of their own so your cam operators can see them, but since they aren't content on your website, it wouldn't matter.
