I don't understand why some people believe that Rockstar might view glitchers with $100 million in the game as a potential cash card customer. Obviously, no one who glitched that amount of money is going to buy a cash card, so I would love for someone to explain to me what Rockstar would be risking by either banning or resetting the glitchers? I see no downside for Rockstar and only an upside for the community, as it would even out the board and players wouldn't get griefed as much.
Even if they don't view them as potential cash card customers, they must certainly view them as potential DLC customers.
The downside is that if they punish these people, then they risk having people who would not buy cash cards, but would buy DLC, become people who will not buy either.
If someone won't buy cash cards if you punish him, and won'y buy cash cards if you don't punish him, then it makes no difference at all, from a cash-card-sales standpoint, whether you ban him.
So, if it doesn't matter at all for cash card sales, you need to look to sales of some other thing to find a potential downside.
That thing is DLCs.
I for one will not buy DLCs if I am punished for glitch exploiting. But I will buy them if I am not punished. I won't buy cash cars either way. It is hard to believe that I am the only person with this disposition.
