Duplicate Content Penalty & Recovering from the penalization

All you you must have heard of this duplicate content penality before also. In every FAQ on SEO, Forum on SEO, Internet Marketing Forums, article and newsletter there is a regular repition of this topic. Just today as I came back from my SEO Marketing company, I logged in to my gmail account and I once again found an interesting email, here a webmaster is talking about how his site was penalized by google due to duplicate content. He accidentaly use some non search engine friendly wordpress template that caused more than 100 copies of index page of his site.

You can read more about this on the forum discussion goin at Web Pro World.

IPL Cricket and SEO

IPL 2010 is beginning on March 12 and being a cricket player in the college time I've a great interest in cricket. IPL twenty twenty is about to begin and I have been a supporter of the Mumbai Indians team from the start of the tournament. Unfortunately the team was unable to do well in both the previous seasons.

Now comming to the reason why I am making this post at SEO blog is that, I just searched for Mumbai Indians to check latest updated from the team I support. Niow when i search "Mumbai Indian" in google. top two site in the results both are having same content in fact one website is photocopy of the other.

My question here is if google doesn't support duplicate content why both the site are enjoying the top rankings. One of them should be banned.

FYI URLS are:

http://75.126.186.214/Index.aspx
http://www.themumbaiindians.com/

Now this is a query you all SEO experts needs to check and answer. :)
