What exploiters do is necessary for the beta, not condoning what they did or their reasons for it. But large scale beta tests have a purpose and these things need to be found and patched and this is just one of the ways that it gets done.
People have to remember that there is a reason that this game is currently in Beta and we are Beta-testing it effectively. These finds are used by the devs to fix this stuff so when it goes to the official release it will be fixed and taken care of.
