Dull days on Adsense - not much going on. Below average revenue. Some advertisers appeared on the stage again. 2 click dumps, sawtooth, business as usual.
And some interesting stuff from the Google Adsense help forums;
This is Andrew from the Ad Traffic Quality Team at Google. We're aware of a problem with a third-party crawler in the network that is generating invalid activity across a number of different publishers. We've recently made some changes to our filtering so that this invalid activity will be excluded more quickly from your earnings reports and the discrepancy between estimated and actual earnings will be smaller.
