I read comics in a RSS reader, ads don't show up, though I've just checked and the only web comics I read that have ads are dilbert, and in linux mode[1] the only non-dilbert related ads are textual, and at the bottom of the page.
I read news, though I don't read any particular newspaper, and news links often lead to pages with ads, but those pages are not sites I visit on a regular basis.
It's very possible I visit sites with ads that I did not see. I don't look for them. If ads catch my eye it's a big sign not to visit that site anymore.
