Any reason why an OSE spam Score is different for www and non-www versions of a site?

[insitemoz1]

When checking the root domain links and DA in OSE pasted a non-www URL of my site and showed up with a spam score of 9.

When I pasted the www. version it showed none.

Does anyone think this is a cause for concern or just a bug?

Are all 4 diferent pages, also may happen to be the home page of a web site. So OSE might get different information for each of them.
I assume that you have your www redirected to the non-www version. In that case, there's a high chance that there are few or none links pointing to that page (www) and it's logical for OSE to score it different.

Have I made myself clear? I tried  making it general
Best Luck.
