I don't mean to sound harsh and I know you personally didn't create spammy ads and so on but if your chosen method of achieving $n per month is to use an ad network that doesn't give a shit about the end user then your business model is the problem here.

You can choose NOT to use them if you want to.

NOTE: I am referring to all content creators that do this: I don't mean to aim at you in particular.

Only "almost all"? Why not use the few that don't? Is it because your revenue from them will be lower? Maybe it's lower because they aren't forcing these profitable ads at your users. That really does sound like the publisher's fault for choosing the most profitable ad network and neglecting the user's experience. Any "good quality" ad network is bound to pay less, otherwise they'd all be doing it.

I'm actually not aware of any except for maybe http://decknetwork.net, which is very selective in accepting publishers and only serves certain verticals.

And yeah, if the revenue from some other obscure network is 10% of AdSense, and a good business becomes not viable, it's not good for anyone.

There are a few, we're one of them: https://news.ycombinator.com/item?id=11902556

Maybe advertising is moving towards being a dead revenue model, and something else needs to take its place.

It must be awful for you poor publishers to cash all those checks from serving malware to innocents. I can only imagine your heartbreak and pain as you accumulate that money, spending it on a your lifestyle in a vain attempt to alleviate the guilt from it.
