I remember back in the day we used to find publicly exposed Windows FTP servers, create new folders using some messed up unicode characters and upload pirated games and movies there to share with each other. The only way to open those directories was to specifically type the exact path in unicode, simply double clicking on the folder in filezilla or windows explorer resulted in a error. Sometimes the admins themselves couldn't delete them and just left them there. Good times.
