Do you use AdBlock?
No. As annoying as online ads can be (especially the really intrusive, in-your-face, bouncing ones), if a site is free it's probably because of ads, so I tolerate them (and even click on the very occasional one that actually interests me). It only
seems fair. But also because I do a lot of online surveys, and (at least some years in the past) some of them are screwed up by ad blockers, so I wouldn't use them anyway.
