Too little too late?
In his latest post at http://ha.ckers.org, Robert Hansen explains that "Google’s detection was too slow to respond to and prevent
the attackers from making enough money to make it worth their while...In lieu of this quality, alternative solutions must be in place to
allow advertisers to recoup their costs while Google struggles to build
new technology to defeat the issue. However, without access to the
actual landing pages that the advertisers use, Google cannot have deep
insight into the full picture. Ultimately, this will cause a bigger
rift with time that the attackers can exploit on the vast majority of
sites that don’t use alternative click quality tools. Until the time
when Google can come up with a creative solution, companies like Click
Forensics fill that void."
