All you can get this way is that you'll still have temporary cookies, removed after closing the tab, you will still have the banner, but this time the banner will popup each time you'll enter the website, because there's no cookie that will tell the banner that it has already been displayed.

I have it like this. But with that, I'm using a banner autoclicker. So the company gets my data, although different each time I enter the website, and I don't see any banners. Win/win?
