Speaking for myself, I'm reading "Some Spammy Queries" as a manually selected list, which gets treated differently than everything else
If that's the case though, it refers to the search terms, not the results. And I suspect it's just a generic catch-all that people are reading too much into.
There are several verticals where all the main search phrases produce "spammy" looking results becase a) there's big money to be made and b) you can still dupe Google with a ton of links and scraped content. You only need top spots for a short time to make a killing so it's one big merry-go-round.
Until Google can work out how to spot authority without links and things that can be easily manipulated, these verticals will always be a target for grey/black hat tactics. Hmmm... maybe hard-coding the results *is* the answer ;)
