It's not as mercenary as anyone giving up their beliefs because they join a site - we're a community and we pull ads all of the time if we find out about them and they aren't good.    Obviously an email is enough but if T. is having a bad day I guess a blog post makes his point also.

We use an ad server chain so when it gets all the way down to Google (meaning, literally, no one is paying to be seen there, often if the same person has been on the same page multiple times in a day) if an article is about religion it will pick a religious ad, which is what he was getting on his article about a dinosaur impression in a church.   The easy solution, though not always acceptable because blogs are personal outlets, is to never write about religion or Rocco or whatever else may get questionable ads, but we'd rather people write about whatever they want.    The somewhat silly solution is to make a proclamation that unless the multi-billion dollar Google company changes its algorithm they will leave.   An advertisement is not an endorsement and only the most militant member of the audience would think that goofy scientologist ads are an endorsement by us.  

Scientologists would never spend money here, because it is a waste of time, so they go through Google and that allows them to only pay for clicks.

If people dislike scientology or anything else that appears because of Google, the penalty is to click on their ads a lot.   That means they waste money and get nothing in return.

If we get any complaints about an ad, we remove it.   Tommaso is not a high-maintenance writer so if he writes about an ad, there is a reason.   You seem to think he is picking on Scientology - had an ad for Catholics or Mormons come up he would have said something also.  It just so happened his article was about religion and he exhausted the premium ads by coming back to that article to reply to comments so it eventually defaulted to Google, which picked a religious contextual ad because his article was about a church.   It could have been any religion using google but perhaps scientology was paying google the most for that keyword at that time.

Thanks.  Google's ad blocking allows a maximum of 64 characters so if blocking www. and just scientology.org as base URLs don't work (if their blocking requires the whole URL) then ultra huge Google is doing that on purpose to keep junk running.

Scientology has gamed Google on Wired, ComputerWorld and too many sites to count the same way as here and Google seems unwilling to do anything about it so, I agree, the one way to get a Scientology ad is to put Scientology in the title.   

But he was on the front page and getting it, as he showed in two screenshots on different days, so that's more annoying to me.   If I block an advertiser I want them blocked.  This reaffirms my belief that AdSense is mostly useless and that is why they are at the bottom of the food chain.
