If showing flashing ads wouldn't have been causing me seizures and if that it weren't the norm to show that kind of ads, what you said could work.

"Here's our content, maybe help us keep producing it by showing our promisedly sane ads?"
I buy a subscription or show ads to 90% of the web sites I visit more than a couple of times per month, as long as they offer them.
