Here's a more complete list of sites that I have found to steal and/or alter the code to games. Many of them I have found to change the code of games to send scores and the like to their servers, so this in an IN YOUR FACE thing:
"ebaum", "ebaumsworld", "rodim", "coolscifi", "dodirectory", "crazy-laberecke", "suprvibes", "simplyro", "40plusarcade", "adventurers-united", "uaenexus", "trackpads", "jl-planet", "rugbyrefs", "spamvault", "necrotania", "loafersparadise", "princejupiter", "johnstownchiefs", "nacros", "suprvibes", "footles", "f4g", "differentdawn", "brentfordalways", "wass-up", "movieloversparadise", "fruit-emu", "usuallygames", "1juegos", "julala", "topsites", "freegame365", "freegames365", "revier.co.uk", "bypassbrowser", "ianag", "gamesreloaded", "freegames365", "in4.pl", "webgames", "gameportalonline", "juegosagogo", "freeonlinegames", "funflashgames", "roffles", "onlinegames", "minijuegos", ".games.gr", "millionsofgames", "juegosagogo", "funflashgames", "technorati", "kbcafe", "gametopia", "70.85.116.68", "briankass", "ianag", "limk", "indi.ru"
It's definitely not complete. These are just the ones I have found to take my stuff.
