PAD didn't kill it. Beyond that, I don't care.
Actually, he kinda did. True, the pages that he didn't want posted were taken down before any action was able to be implemented by Marvel's legal eagles. But it WAS he who brought the site to their attention, rather than just complaining to the site's moderators. And it was Marvel's legal department that sent the notice to LiveJournal that likely threatened legal action if they did not kill the site. PAD set the whole demise of scans_daily 1.0 in motion, and saying he isn't responsible for that is flat out wrong, legally justified or not.
I, for one, had taken that because the site wouldn't allow for more than half of any one book to be posted and the participation of several comic creators on the site that Marvel and DC were both already in the know and gave it their silent approval. It was very much like a preview and review site which spurred many of their users to buy titles they would never have given a chance without. You could go to a library and read much more than they ever posted.
But, technically, it was a violation of copyright laws. Its days were numbered from day one.
