It troubles me somewhat that I get all this internet stuff for free, but am able if I want to to disable the ads that keep it free (yes, I know that I pay more for the stuff in the ads, etc....), so I've never used ad blockers. I do tend to not invite weird ads as I don't do weird internet stuff, but I suppose that the odd accidental fat-finger click can have, er, unusual stuff raining down on me. I think that has happened to me quite a few times. It doesn't bother me much.
