Nonsense unidentified guest! Google is putting up ads based on our interests as expressed on the forum.
Jack, just because the unidenrtified guest left the "from" field blank it doesn't make him or her wrong and you right.

As somebody who has run Adwords campaigns I can tell you that click fraud is a problem that G takes seriously.

They regularly disallow clicks, I know because, as an advertiser, I have had refunds.

If they disallow too many on one site then that account may be closed - FACT

If they think that the publisher has been soliciting clicks then the account may be closed - FACT

IF the account is closed any unpaid funds in the account are forefit - FACT
