Via David Weinberger, I see that truth continues to be stranger than fiction. I don't think I would have believed that a (trying to be) serious "Captain Copyright" site exists unless I saw it myself. So it looks like I'm violating their policy by linking, because of this bit from their access rights page:

"Permission is expressly granted to any person who wishes to place a link in his or her own website to www.accesscopyright.ca or any of its pages with the following exception: in order to protect the moral rights associated with this site, permission to link is explicitly withheld from any website the contents of which may, in the opinion of the Access Copyright, be damaging or cause harm to the reputation of Access Copyright. Specifically, permission to link is explicitly withheld from sites featuring pornographic, racist or homophobic content. If you link to or otherwise include www.captaincopyright.ca on your website, please let us know."

Heh - cut down, that says: "You can link to us only if you agree with us. Otherwise, not so much". I think I need to quote Bugs Bunny: "What a bunch of maroons!"
