Hmmm I get the feeling that one of your &#x27;sources&#x27; for the db comes from the users who have already installed your app. Just a tin-foil-hat hunch based on the density of nodes in certain areas (read: certain routes). Too bad 60%+ are HP-Printers or vmguests...either way it&#x27;d pay to clean all that up if you&#x27;re promoting that they&#x27;re free&#x2F;open hotspots.
