Dear El Reg
Isn't it about time you had a report ad button, as a way to catch mis-behaving ads? There are quite a few of them, and it's bad for your reputation - and yet does no harm to the reputation of the unknown ad network that foisted them on you. Your button should push a complaint to you for action, and maybe copy in the network as well - to let them know they're pissing off potential customers. Maybe the final ad client as well?
You had that O2 campaign a few months ago that went wrong. Yet you were contracted to run the bugger for a whole week - and it made the site un-visitable. I did read a few stories in whichever browser I found the ads didn't bugger up (my iPad I think). Obviously a nice report to the ad network had no effect - why would they give a fuck, it was your reputation that got damaged? But a few grumpy and possibly pithy comments from El Reg commentards via a complaint button may have woken O2 up to the damage they were doing their own brand image. Even if not, it would have allowed a few of your denizens a chance to have a good old vent. Satisfying at least.
P.S. - I see no cleavage. I have a chap in a polo shirt, and an odd constipated expression with a cat and an O2 logo. He's apparently an O2 Guru.
