This is a simple problem to solve.

Charge for access to your site. If people are not willing to pay for it, it’s not market-viable anyway. And should return to dust.

I don’t want to pay to access every site - especially those I visit only once.

Just eliminating the pop-up adverts would be enough

In my view, the best solution is to simply insert ads right on the page, preferably in a sidebar.

If I see an ad that interests me, I'll click on it. Popup ads, on the other hand, are the spawn of the devil, and should be blocked by visitors.
