(b) I have a relatively sensitive LLL domain that I had set the keyword to investment, considering it has been 2 different investment sites in the past and this is generally what the traffic is looking for. To my horror, I find out that US traffic is seeing specific "Trade marked acronym" adverts totally unrelated to my keyword, which is exactly what I didn't want to happen. 
Not happy, and I have pulled this name, I don't really want a UDRP on it thank you very much parked.
