My blog, spam?

Aww after a long time I log in to my blog, just to see a warning message that my blog as been flagged as spam blog and it'd be deleted in a few days! I was really shocked. I'd really hate to see my blog being deleted, coz I love this blog so much and though I am not so frequent, I am very much attached to it :). I followed the link to Request Unlock. Well, I have done that now, of course.

I really am not sure why this has happened. I just now went through the Terms of Service and other links, and came to know about "link spamming". hmmm.. some days back I had participated in a site to save tigers. There was an option to spread the word through various means. like in my twitter account, facebook or blogspot. Oh, I thought, I can spread the word about this good deed in my blog and I did publish it in my blog from that site. The post has a link in it. Maybe this is the reason for my blog to be termed as spam? I don't know really. If this is the case, then why allow third party websites to give options to publish their contents in blogspot directly?
