So, I'm monitoring traffic and clicks because I suspect a click bomber and I notice clicks coming from an address that is identical to my blog address but has a www. in front of it.  So, I'm wondering if this is part of my real blog (like the new country specific addresses -.ca etc) or if this is somehow a false site that someone has erected with my content.  When I go to the address, it is my exact same site, so I'm inclined to think it's okay.  

Here is what I mean...

My real blog address is something like:  http://myblog.blogspot.com
The address that is showing up on my log is: http://www.myblog.blogspot.com

Do you think this is okay or something I should worry about?

Thanks!
