Google Discovery alerts about a strange blog insite Orkut's server.

Example:
http://blog.orkut.com.br/2009/09/big-bang-theory-s03e02-legendado.html

http://googlediscovery.com/wp-content/uploads/orkut_blog_fail.jpg

Example: It's not there anymore

Google removed the pages, but the subdomain still exists.

The odd thing is that the DNS records for this subdomain were from Google servers (blog.orkut.com.br. CNAME ghs.google.com.), so this must be a Blogger exploit, or something Google Apps related.

Hope Google reports what happened eventually.
