Watching my Blogspot analytics i saw several strange-looking domains, like
bd053ac3.any.gs and others. So trying to identify them i got the following:
bd053ac3.any.gs - shows "Link not found" page
any.gs, dyo.gs - goes to linkbucks.com
Yes, my blog uses AdSense, but i don't advertise it. So i wanted to understand why this can happen?
