Same problem, adds are being pushed out by Admob a Google company, I have tried every thing and nothing stops them. However I have found a way to make advertisers cancell advertising with Google, Doubleclick and Admob.
Either fill in the advertisers proformer and tell them to F$@k Off, or find the advertisers email address and tell them to F#@k Off. dont hold back on the language and do it repeatedly.
I have had advertisers contact me and after discussing how much it pi@@es me of they have appoliged and said that they are going to cancell their advertising with Google.
If over the course of two weeks I can get 5 compinies to cancell their Goolge advertising, imagine what damage it would do to Google if 10 thousand people do what Iám dooing.
