I had the same problem as bumpski. After putting referral buttons online yesterday, I had twice as many impressions as usual. My earnings were normal. But today, my CPC went down to the basement (1 cent per click, where usually I get 0.10-0.20) and my earnings with it. I pulled off the stupid referral buttons. It seems they are screwing up my site and stats.
They look dumb anyway with their rounded edge on a site that is primarily rectangled.
