In these two cases, they look like they are articles written solely for the purpose of SEO. (1) The fact that these specific articles are splattered across the net, and (2) they both have a ridiculous number of inline links to the same URL with the same keyword ("brake bleeder" in the first example and some permutation of "wholesale sexy dresses" in the second) make it obvious to me that this is SPAMMY SEO. Let's call a spade a spade.
While I'm for SEO, I'm vehemently against SPAM. Far too often, they overlap.
DELETE!!!!! We're trying to make a product wiki after all, not a spam-haven.
