In any case there's plenty of sites which are now offline / expired etc but still show in the link profile. How long does this take to update?
You might be waiting weeks/months for Google to recrawl a page that's off the beaten track somewhere in a dark corner of the web.
That page might even then need to be recrawled a further time, just to check it is definitely offline. Then it'd take another couple of weeks for that to be reflected in GWT.
