Is Google Failing to Enforce "Quality" Ads?

We have the usual eBay junk (any word in the dictionary will do, even if the landing page is just 6,200 results of stuff that have parrot somewhere in the description of some product), and then, even weirder, something that directs the user to a SERP on Ask.com. Ask is promoting their search engine in Google ads; because the Ask SERP's are fairly heavy with ads this looks semi-arbitragey in intent, but from a user experience standpoint, definitely violates what Google says users hate - getting another page of search/ad listings, after clicking on a search ad listing. I'm sure IAC has plenty of money for this branding exercise; only they know what they're paying per click.

In fairness, pages of ads on any generic, one-word term are bound to look stupid. And Google's already indicated that their minimum bid policies might be relaxed in markets (countries) that are "less mature" (read: fewer ads). Nonetheless, this example does seem to show that as dead as they may be in Google's rhetoric, once in awhile, users still get to admire the beautiful plumage of the odd prime specimen of "garbitrage" and "double serving cheaters."
