Why does Blogspot automatically creates .co.uk, .jp for my .com blog?

I have a .blogspot.com.
When I searched for it in yahoo, it showed me (my blog).blogspot.jp and (my blog).blogspot.co.uk

All of these had the same contents as my blog.
But in google it does not show these 2.

And I never created or opted for .jp or .co.uk.
How is it possible?

This might have something to do with spammers. Basically, Google uses your geographic location to tailor the results that you see when you search. Domains associated with a particular country are given priority for a given keyword. So if you were searching for IT Courses in the UK, you would see more .co.uk domains than .mu. Now it might be possible that spammers are trying to use your content (blog posts) for internet traffic. They use software to automate the whole process of cloning a site.

However Google has come up with a duplicate content penalty and therefore it would not index or penalise a site which has been copied. This would explain why your searches for these other blogs returned no results.

Oh. Complicated! Wonder who has time copying my blog. Perhaps that's why in just 2 days my blog has become 2nd in google search results. o_o And it changes place constantly on the first results page.
