I have several times brought this up with various bits of G, most recently in response to an unsolicted mail from G in Ireland offering to help "optimise" my use of AdSense. The people in G variously respond with boilerplate or that this targetting miscue is my imagination or that it cannot be fixed, and my last email conversation stopped dead!
ASA: please get your CSR and "optimisation" and targetting people:
1) To get their story straight (and stop denying what is a very definite and comletely understandable mis-feature in an otherwise clever/good heuristic).
2) To allow occasional manual fixes (essentially a regex to zap URL components for some sites, and a small list of -ve keywords too) to overcome small wrinkles in the algo. Note that these should be fairly abuse-free as they will be BLOCKING ads rather than attracting undeserved ones...
Very little about G irritates me, but calling the customer a moron or stopping the conversation dead, is one of those things that does.
