I'm a little over 400,000 in referral bonuses these days (I promote the network a lot, and have a very large user base to promote it to). And, anything pointing to the ad network directly doesn't come from my weight. It's the default ad (if a user's ad is picked and they haven't setup any ads on their account yet). But that's not to say I don't run ads either... I'm currently running them on 6 sites I believe.
