Technically, the Rubble Glitch does fall under EA's No Glitching policy in their
ToS:
"Use or distribute unauthorized software programs or tools (such as "auto", "macro", hack or cheat software), or use exploits, bugs or problems in an EA Service to gain unfair advantage."
However, it's far too easy to accidentally get into for any sort of 3rd-party global ban.
Not that people aren't allowed you call you a "coward" or a "cunt hiding in the rubble". Maybe just don't exploit it, if you don't want to be called mean names, since there's no record of anyone deliberately kicking you (yes, I did check).
