There might be a slight difference but it's so easy to host content remotely these days and claim to be "just" providing links. The law isn't that dumb.
Are you suggesting he may of hosted the content under pseudosites that were at face value unaffiliated to him? He may well of done, but in that case it will be up the law to prove he owned and ran the sites containing the illegal content. I doubt he did as compiling his library of links seemed a full-time job anyway.

If he's just found guilty of linking to the sites though I can see him getting a fine at most and moving his site to the Netherlands like so many others.
