I just tried it on the getpaint.net site (mentioned elsewhere itt) and it only had an option box set with three options: inappropriate, repetitive, irrelevant.

I just tried it on the getpaint.net site (mentioned elsewhere itt) and it only had an option box set with three options: inappropriate, repetitive, irrelevant. But you could just right click and copy the ad link. The link would point to the ad network (e.g. googleads.g.doubleclick.net/aclk), but it would be better than nothing. Also, many ads include a domain, sometimes in a tooltip, and usually just the tld, but again, better than nothing.
