This is not strictly speaking political. However, a lot of people on here have their own blogs.
If you're using Google AdSense to generate revenue on your blog, and your blog is somewhat thinly read (or maybe even widely read) you could be in danger of losing your account.
It works like this: Someone goes to your blog, and tries to be supportive by clicking all the ads, refreshing the page, and repeating several times. Google flags this activity as a click farm and shuts down your account without any warning.
It happened to me, it can happen to you. Of course, if you're a dirty tricks kind of person, you can target opposing blogs with Google ads, and ahem "show your support."
