Google's spam-fighting system is apparently too good. A couple of years ago, Google accidentally mistook the company's own Custom Search Blog as spam. The Google blogging team in charge of updating the website didn't notice the warning messages indicating that the blog would be deleted if the user didn't clarify that it wasn't spam. When the blog was automatically deleted, another Web user took over the domain name for the site. The Google bloggers initially suspected an external hack job, but then they realized what had gone wrong. They got the domain name back — and then presumably blogged about the whole ordeal.
