What Happened to Blogsvertise?

Tweet

I've been earning from Blogsvertise since 2008 and until 2009. And for this year, I haven't receive any assignment tasks yet, instead what I received from them is a news letter about the site, informing me the latest updates they have. However, just today I can't open the site and what I get is a pop-up message like this "A username and password are being requested by http://www.blogsvertise.com. The site says: "developer only". Been trying to search the answer in the internet might be someone posted something about Blogsvertise but can't find one. Does anyone here who also have accounts with them encountered the same problem? What happened to the site?
