Ok, this is an interesting question. I am a homebrewer, and really love beer. On my personal blog the other day, I saw an ad for a local brewery tour that I had never heard of. I was really interested in it - but I know clicking your own ads is verboten. The thing is, I couldn't tell anything about where the tour was actually organized, which really leaves me no option but to click the ad. Has anyone ever been in a situation like this? What should you do? Email google?
