Hacker Translator will translate any text you input into 'H4X0R' text. The idea of 'H4X0R' text is to replace as many letters with numbers/symbols as possible. Therefore, Hacker Translator would be 'H4X0R ?r4||514?0r'.
Version 1.15: You can specify which direction of translation you would like, and you can also randomize the character translation process via the preferences window.
