title: "Bad" file extensions that should be avoided on a file upload site?
body: <p>Im re-writing a file hosting site, and I want to have the ability to host every single file type (instead of just having a whilelist of allowed extensions).</p>
  
  <p>Im running nginx and linux. Site is built in php. I'd disable th upload of .php files.... but other than that.... is there anything else I should watch out for?</p>
