Apparently Google has refused to run ads on PrestoPundit, a fellow Bear-Flagger, due to "sensitive content". Fortunately, Greg Ransom says he makes plenty of money from his "readers and they continue to generously donate enough to pay for most of my bandwidth. And book sales cover the rest." He thinks it's related to his coverage of Rathergate, but who knows?
If a blog actually turns a profit then there doesn't seem to be much to complain about. I'd be frustrated too if I was blackballed by anyone, but I'd rather get contributions from readers than sell ads. Still, Blogads is a nifty service and well worth it, for me and for my advertisers.
After the story appeared here on Master of None Google quickly reversed their position and unblackballed PrestoPundit.
