Is this SPAM?

Just wondering, that's all.  I see that quite a number of people have had their blogs classified as SPAM, and are having some difficulty reasoning effectively w/Blogger.  What's up with that?

I'm trying to determine if this is a software or operations anomaly which will at some point be remedied, or if there's something more evil going on, which I have seen alleged.

It appears that when a blog is declared SPAM, the specific rule that triggered that declaration is not cited for the blogger.  Why not?
