Users more annoyed with adsense?

It really depends on the type of blocker used. Some purely set the visibility and/or size to zero through CSS. In this case the impression will register since the script does execute.

 

heh, my frontpage contribute 20% of my total revenue. How can I remove the ads there.

 

I also only use 1 set of ads on my site, not to annoy my visitors too much.
