Impossible Spam Traffic in Google Analytics on a Ghost Tracking Code

Some months ago I created a tracking code for a new website in Google Analytics. I never registered the domain name and I never added the tracking code in any page. After a few days I totally forgot about the code.

Today I saw that the website, that I never registered, had 243 visits. You can see in the image that the URL is not registered. How come?

I always struggle with the spam traffic problem, but I never thought that Google Analytics could have so many glitches.

I’m trying http://gaspamfighter.com/ to get rid of the spam.

Does anyone know why I’m receiving spam traffic even if I never used the tracking code?

Google did you know about this issue ?
