I use an ad-blocker (and have done for some time), but I have it disabled for this site. I would encourage others to do the same, especially if the excess revenue is going to benefit projects like this. I know some people do have concerns regarding privacy etc, and I detest when web sites are bogged down by the sheer weight of adverts, but to my mind it's a fairly small sacrifice to make for good causes.
Do accidental clicks contribute to this revenue?
