I pick up the paper and look at the headlines, but adverts start filling the page and the headlines keep moving about. When I'm reading an article adverts keep appearing in front of it and I have to swat them away, and when I turn the page the ads move across and cover the next article. And one of the ads gives me a reading disease and I can't read any more papers until I'm cured.
That's what online is like without an ad blocker. So, definitely no guilt.
