About the SPAM: I think that R. meant that spammers use emailadresses they find on forums and newsgroeps to mail their spam to, not that he was gonna do that himself, he he...
About putting a link up here, a normal link to a site: that's legal. Taking some info from a site and not name the source: that is not done (copyright). e.g. when I find lyrics to a song, I cannot put them on a site of my own without mentioning where I got the lyrics. It is nettiquette to put the url under the link where you found the lyrics, and most people put underneath: "courtesy of...." and there the name of the webmaster.
R. was clear about not wanting a discussion about linking, though. He said: "NO URLS". So no URLS it is. :)
