When I search for Limewire on Google.

www.limewire.com which is the relevant result

PC-world (a review of Limewire + free download

www.download.com (free limewire download)

etc.

+ Not a single sponsored result

are you sure that you don't have something on your PC that redirects you to some scam google-site

I am not saying that I have never gotten bad searchresults from google, but at the same time I will state that out of all the searchengines I think that Google is the best and most helpful

You should try searching with some of the other searchengines out there and you'll see what I mean

As for sponsored results

If you had created something brilliant, wouldn't you like to get paid ? I sure would
