Your board will go to a cut-rate prototype PCB factory in China. In all likelihood they have too much volume to give a crap about what's on your PCB, but if this is a concern PLEASE FIND ANOTHER SUPPLIER. We intend to make Dirty Boards for open hardware enthusiasts who WANT their designs used and propagated.
This site was intended for friends and not the public. We'll process your boards, but we only make about 30 cents per order. We really don't care if you want to take your business somewhere else, and it's not worth our time to deal with stupid questions or asshats. Paypal fee reversals, annoying emails and the like will get you banned from the site.
