rabbit1, posting a warning to authors that they are not retaining the rights to their stories is hardly making a circus out of anything. Your comment is demeaning and insulting to both the original poster as well as subsequent ones.
And as far as comments not changing anything, including yours or Tiger's minds, that too is absurd. If you do not feel that this site needs to be responsive to the concerns of the authors and/or readers, then you should not be running this site as it is designed for both. Or have you simply overlooked that point?
I understand adhering to the law, but this has little to do with legal ethics (except for copyright law as Ruby has already pointed out) and all to do with the morality of ignoring authors' requests, particularly without policy and simply on a whim.
