On one hand I hate the fact that many sites have been set up just as addsense money making directories with very little content and have risen to the top of my sector just through getting other sites in my sector to link to them only to turn tail and fill thier pages with addsense adds and put thier links a million pages deep.
At last a way to punish them!
However as most of them sit on the top for related keywords, Joe user is still clicking on those sites as the average user doesnt even know the difference between an addsense link and a wombat.
If I decide to block those sites i'm going to end up losing those clicks.
