I spent a few minutes going over the Dropbox Terms of Service. The section I believe that they are referring to when they removed the public link is: General Prohibitions You agree not to do any of the following while using the Site, Content, Files or Services: Post, publish or transmit any text, graphics, or material that: (i) is false or misleading; (ii) is defamatory; (iii) invades another's privacy; (iv) is obscene, pornographic, or offensive; (v) promotes bigotry, racism, hatred or harm against any individual or group; (vi) infringes another's rights, including any intellectual property rights; or (vii) violates, or encourages any conduct that would violate, any applicable law or regulation or would give rise to civil liability; ...

Full Terms at: https://www.dropbox.com/terms#terms https://www.dropbox.com/terms#terms) Seemingly not only is posting the code for DropShip a violation, but just by me putting up this file ( http://dl.dropbox.com/u/1498040/2plus2equals5.txt http://dl.dropbox.com/u/1498040/2plus2equals5.txt ) in my public folder, I'm also violating the Terms, as I am publishing text that is false and possibly misleading.
