If you read the blogger content policy, you should read Enforcement of Blogger's Content Policy below :

If you encounter a blog that you believe violates our content policies, please report it to us using the 'Flag Blog' link located at the top of each blog (Note: If the blog owner has hidden this link, you can still report the blog by filling out this form).

Our team reviews these flags for policy violations. If the blog does not violate our policies, we will not take any action against the blog or blog owner. If we find that a blog does violate our content policies, we take one or more of the following actions based on the severity of the violation:

* Put the blog behind a 'mature content' interstitial
* Put the blog behind an interstitial where only the blog author can access the content
* Delete the blog
* Disable the author's access to his/her Blogger account
* Disable the author's access to his/her Google account
* Report the user to law enforcement
