Hi!
great question and great answer
we were wondering on implementing such ads on our sites
(just 1 per person per day, so it wont appear to the same user twice or more times on the same day, just if they delete cookies)
so really good news it is not penalized (yet) by Google but its also true inst a gtreat user xperience for visitors..
so maybe you should just take one of those networks and not both .. dont now, try and let us know!
