problems with squidoo URL

After analysis of strange behaviour of one of the squidoo lenses I've jumped into the conclusion that for everything bad is responsible
multiple way of addressing the lens URL.
The lens used capital letters in name Krakow-Travel and that was accessed and linked by squidoo pages, but squidoo server does NOT recognize capitalization of the letter.
When you want to access the lens by putting krakow-travel the server does not return 301 or 404 code but 200.
The result: in Google there are two pages with duplicated content.
Punishment.
I have not observed it for a long time, it appeared that G has chosen the small letters version, but with some filter, that may or may not be taken off in the future.
So far the whole lens has been corrected to:
http://www.squidoo.com/krakow-travel
and we will see if the filter will be released soon.

The photo is less about my thoughts of squidoo, more is about the way of hitting competitors, who happen to have capital letters in squidoo url.
