An apology from Blogger

Blogger Buzz: You Are Not spam:

We want to offer our sincerest apologies to affected bloggers and their readers. We’ve tracked down the problem to a bug in our data processing code that locked blogs even when our algorithms concluded they were not spam. We are adding additional monitoring and process checks to ensure that bugs of this magnitude are caught before they can affect your data.

At Blogger, we strongly believe that you own and should control your posts and other data. We understand that you trust us to store and serve your blog, and incidents like this one are a betrayal of that trust.

Nice of them to recognise it. Certainly the thought of losing the million-plus words I've posted since I started blogging (or at least losing easy, serchable access to them) was rather frightening.
