// Profanity syntax:

// window.profanities.push([/SWEAR WORD/gi,"<span class='DJCReplacedProfanity' title='[replaced profanity]'>REPLACEMENT</span>"]);

// You'd copy the above line, remove the "// " at the beginning, and replace "SWEAR WORD" with the profanity and "REPLACEMENT" with the replacement.
// Please note that if the swear phrase contains any of the following characters, you must place a backslash before them: \.$^*()+[]{}:.?/
// Similarly, if the replacement phrase contains double-quotes (") you must put a backslash before them as well (\")

// Also, replacements that you want performed first must go first. For example, if I want to replace "fuck" with "123" and "fucker" with "456",
// I'd have to replace "fucker" first, otherwise "fucker" becomes "123er"
