Updated: the whole fraud story.
I sent the full complaint email on Friday, letting them know about the
click fraud problem. Probably moved into a higher priority queue than
regular customer support stuff, their reply came back the same
day. They are investigating this issue and will let me know as
soon as they have more information about this.
We are currently working as quickly as we can to
investigate this issue. As soon as we have more information for you, we
will email you again. We appreciate your patience.
hope the Google Click Quality team will investigate this soon enough.
I'll let you know how this stuff works out. Meanwhile, I disabled all
Content Network matches from Adwords, because it seems that there the
most faked clicks happened.
