question regarding marking a blog es archives or deleted or spam

I tried marking an old unused blgo as archived thinking it would no longer be accessible thus giving the owner a chance to redeem his blog, but nothing changed. hte blog URL was still working jsut fine.
Next I tried marking it as deleted and then spam and still the blog is accessible.

Are these options broken?
Using wp 3.0.1 with multi-site

can you give it a try? see: http://screencast.com/t/MjYzMDlhNzM you can try the url from the screenshot, the blog is archived, spammed and deleted and still accessible via http://cineva.zice.ro/
