Seems to be true, even I have heard people saying that.

But then more ads would'nt be something like more chances of getting clicks???

Lately what I observed was when you have huge traffic from the social networking sites your CTR and Pay per click decreases rapidly. I actually tried it with one of my site where I used all social bookmarking tools to bookmark my site and I had around 500 to 1000 uniques every day from that. But my adsense earning drastically decreased. Every click only paid me around $0.01 or maximum $0.03.

Again this month I did not bookmark any of my post to any bookmark site and left it over the organic traffic what it gets and was surprised to see that after a week I again started getting 3% CTR and around $0.10 per click.

May be someone else should try it out to confirm it too.
