I'm a bit surprised that this blog hasn't been hit, since I write quite a bit about Obama, and not in a flattering way. But I can guarantee that if I do get locked out, I'll probably move this blog to a censorship-free zone, as, I suspect, will many of those who are targeted in this way.
Blogger, and Google, ought to be proactive on this if they're not condoning it. They need to make it just a little bit harder for someone to freeze a blog--a single unverified report of possibly objectionable content shouldn't be enough automatically to remove an author's access to his/her writing. And if they don't want bloggers abandoning their service in droves in favor of Wordpress, Typepad, Vox, or any of the other available blog-hosting platforms out there, they need to get on this, pronto.
UPDATE: Please see this update at CMR. Apparently, this is a widespread problem that Blogger is working to resolve.
