And at least Google iAds give you the tiny little logo in the corner for you to click so you can report the ad that tries very hard to look like a download button :(
Google: here is x dating site,
Me: click, mark as irrelevant.
Google: here is y dating site
Me: irrelevant
Google: z dating site?

Google: lets try an ad for x dating site again then

Somehow Google think dating sites fall under auto repair, gardening, computer hardware or software or a few other categories I am actually interested in.
Or more likely IMO: they don't care.
