I think it is already over, I am not certain if twitter fixed the issue or not but they certainly stopped it for now, of course it may take some time before they can fix it or not (or maybe it is fixed already) but at least I am aware of the fact that nothing like that has happened since that day, they have stopped for the past few days I think.

However what has happened has already happened, dude has already stole as much money as he can, obviously an idiotic method to get money but he did grabbed hundreds of thousands of dollars last I checked, maybe even millions now that I haven't checked in a while. This is why I think even if it is closed, the amount of money that was stolen should be taken from twitter and given to people who paid that money because twitter did played a role in this with their lack of security.
