// Details:
// --------
// Given a list of user profile IDs ('Trolls'), this script will minimize their voice
// by performing the following actions to each of their comments:
// - Prefix their name with the string "Troll: " for quick identification
// - Fade out their name and date of their comment to be 80% transparent
// - Hide the body of their comment text
//
// Additionally, if you MUST read their comment, you still can.  Simply hover over
// their name and their comment text will be revealed.  Move the mouse off their
// name and the comment will disapear again.
//
// Finding a "trolls" profile ID:
// -------------------------------------------
// 1. Go to a projects comment page
// 2. Click on the "trolls" user name to see their profile.
//    The url of their profile page ends with a long number, for example:
//        https://www.kickstarter.com/profile/xxxxxxxx
// 3. Add this number to the "Trolls" array below
//    NOTE: you can add as many ID's to this list as you want, as long as the
//          result is a valid Javascript Array object.
// 4. Save this changes and enable/activate/install the script in your userscript
//     extentsion or plugin, such as Greasemonkey or tamplermonkey

// Trolls:
// -------
// The `Trolls` Array.  Presentation of comments from these profile IDs will be
// modified so they are easier to ignore.
// Each entry is a single quoted string that contains a KickStarter Profile ID 
Trolls = [
    '0000000000' // Replace this one with a valid profile ID
];

// WARNING:
// --------
//     Unless you know what you are doing, DO NOT mess with anything below here!
