I don't know of anyone that likes the blinking or "earthquake" banners or the popups. But there's not a lot CC can do about them.

He signed up for an advertisement provider, who in turn will provide him with the ads for this site.

He can probably restrict a certain number of ads, but not all of them. Plus, if he doesn't meet a certain "quota" set by the advertising provider, he may loose his account (some set limits such as a minimum of 50,000 ads per month displayed, or 50,000 unique viewers a month, etc, etc.).

If he looses that, he'll have to pay all of the fees associated with this site through his own finances; which may lead to the demise of this site if he can't cover it all.

Please consider that everything costs money. Some people even pay for the sun (solar electricity).
