Have you seen the threads posted by /u/Code_Marathoner on the Battlefront Subreddit?
This is the latest entry:

He found one of the free hacks and has been analysing it over the past few weeks.
He's also trolling the hack forum admins and the hack author, it's hilarious to watch. He's basically shown that the author is literally a whiny little high school kid trying to look cool.
His latest accomplishment was revealing that putting "hex" in your username broke the hack against you almost totally because the author is a noob coder.
He says the author is going to "surprise" everybody who tries this trick, but he says that he's hoping the hack will autokill everybody who does it so that all the hackers who try to hide their hacks get busted. I've put it in my name, haven't seen anybody try to hack.
You have to read back through the threads, especially the comments on part 2.5, the amount of salt he gets from the author is pure gold.
