This is from Blogger.com's rules.  I've become painfully aware of it because they deleted one of my blogs.  I created it months ago, had 5 backlinks from comments on people's articles.  It was pointing to one of my sites.  And no, it was not designed to drive traffic to my site.  This one was designed to allow me to play with things.  The last thing I did with it, is put Amazon.com ads on it, wanted to see how it looks, how it works, where they work better.

Yes, it did point to one of my sites.  But as I said it was not designed to do any of the things they consider spam.  It was where I thought myself how to create a blog, hyperlink, make a clickable image, etc.

I post this because I think a lot of people don't pay attention to that clause and because what I think I designed the site for and what Google thinks the site was designed for aren't the same things.

By the way, they delete it and there's nothing you can do about it.

Spam: Spam takes several forms in Blogger, all of which can result in deletion of your account or blog. Some examples include creating blogs designed to drive traffic to your site or to move it up in search listings and posting comments on other people's blogs just to promote your site or product.

Create your blogger sites at your own peril.  If you do hide the fact that you've designed it to drive traffic to your site, presumably by not posting on the same niche more than once, by sending traffic to E-how.com or some other such sites.

 Any other ideas?

PS.  There's no green cow in this story.  It's merely false advertising.  And if you're reading this paragraph, it damned worked.
