I hate websites like that, and avoid them like a bad disease. A waste of time to click repeatedly for dozens of items that could easily be displayed on a single page. I never look at the popup ads, and delete them immediately without reading them. Also, websites have teaser thumbnail pictures to entice you to go to the page but never show the referenced picture, forcing you to click forever looking for it. I hate those websites and never go back.
And there are a ton of them.
They are bait for the advertisers and they never get to the point or give you the information until you have clicked through pages and pages of advertisements. They are a scam. People will eventually figure it out like us and avoid them.
