What rockstar may or may not have done to glitchers I'm previous titles is.immaterial. in this game they are intending making bucket loads of cash from micro transactions. That fact alone is a game changer and imo makes ituch more likely they will act against those who have effectively stolen in game currency from them.
It will be interesting to see what transpires
interesting... but my opinion is that R* already knows it dropped the ball big time on this and is the primary cause of their loss of income( so far not being able to sell the cash cards)
So I don't think they will come after people who used these exploits due to faulty coding.
Im sure heads are rolling in this company as we speek because of certain people in certain positions and their inability to do the job correctly on a major project.
When the system is completely patched and its working correctly...R* will sell all the cash cards to all the good guys who don't cheat and move on.
