Advertiser opt-out of specific AdSense sites?

Any chance of this happening?

My online service, aimed squarely at corporate customers and costing in some cases several thousand pounds is being advertised on a kids site.

I'd love such a service.

I had lots of hits coming in from a site, and those visitors didn't convert at all. I had to disable content-ads for this whole campaign because of this. It would have been better to just disable one url.

Enabling and disabling per adgroup would be much better and should not be such a big deal I would expect.
