Oh, that definition of "spam" isn't really relevant. (Outside of the "News" categories, of course.) Most informational content can be quite "old" and still useful. (Its use changes over time, of course.) And a corporate website may not change in structure, while its actual content is an up-to-date database (for instance, of items for sale, or scheduled performances).

But in my experience (looking at, for instanct, older site submittals) I simply do not see the pattern you hypothesize.
