so why are you supporting them with this PR?

(Tomáš, I reported on this because DoubleClick is serving the ad, and DoubleClick is owned by Google – so Google is once again making ad money from services which are against its own webmaster guidelines.)

Yes but the problem is not with doubleclick and not with google, but the advertiser, who is doing something against rules. And there are tons of such advertisers, and no of them recieve link from your quality site, nor unpaid article, which may interest someone to buy it. IMHO the better way is just to report the advartisement against rules and then simply ignore it.

Did you report it, and if so, could you tell us about the process of reporting it? Do you have any experience with the feedback DoubleClick (or Google?) gives in these situations, do they write back and block an ad or...?
