iPhone?
I am going to try allowing only one ad-network each day on iphone/safari for the rest of this week.
Please report here at the end of each day whether you see any problems or not (first time this will be active is tomorrow) - NB this will only apply to iphone/safari comination.
Also those of you who are having a problem, it is equally important to let me know if a day goes by without problems, as I can then assume that network is a least temporarily clean.
I will be removing the cookie which restricts the ads you see from an individual network, which means that temporarily the problem might get worse when we find a rogue ad - but at least we should find out anyone who is sending them.
