SEO from Free Blog--Asking For Help

[sonata06]

Dear Friends here
I am a junior SEOer from China.
I registed a free site in this link: www.indonetwork.net
My site is : http://indonetwork.net/cheerwetelecom

I posted Spam in Google groups for SEO last week.
And SpamCorp reported my site: http://indonetwork.net/cheerwetelecom
as a spam site.

So "www.indonetwork.net" deleted my link from my site...

I am considering that is it possible to post message in a free Blog,and do SEO.
So that Google could get more informations from my Blog.

Is it ok to post my site's sitemap on a free blog for SEO?
My sitemap is:
