One of my buddies that got into SEO a half decade before I did mentioned the copy and paste rankeroo stuff was real popular back in the days of Infoseek, Altavista, Excite, Lycos and similar.
Google looks for the canonical version of a document and then deduplicates before returning the result set.
You can add
&filter=0
to the end of the search URL for a particular query to turn off the duplicate content filters.
An old school spam technique for some affiliates in the early days of Google was to buy a high PR link to their affiliate URL so that like site.com/?aff=123 would be the default version of the homepage & the branded searches for the merchant would then owe the affiliate the commissions until the rankings shifted again.
