This is not true. Views are being affected. Sedo has been provided evidence of this and say they are looking in to it.
I'm all for fighting click fraud but Sedo needs to be open and honest about what they are doing. In this they have failed miserably, repeatedly delivering canned responses with bald face lies.
It would have been so easy for them to simply have said they were testing ways to reduce click fraud and apologized in advance for the inevitable problems this would cause for users. Most people would respect and accept this. They really screwed up on this one, and potentially it could cost them big.
