You might be okay, but I would try to get some insider info on how AdWords Analytics companies get away with it. Might just be sneaky bots. A lot of idiots write code that pings or loads google.com to check for internet access so they can't block it completely.
The good news it's that it's reborn as an ad support version. Google doesn't want your dirty cash when your competitors are willing to pay much more for ad placement on your site.
