also note that waiting around for those that exploited could take weeks. not everyone plays every day or is it safe to assume those that have partaken in the exploit played everyday. they could very well be ones that played on weekends, played every other weekend, played on days off from work (once or twice a week). As such, this window of opportunity may not be known to them and may only serve to have a fraction of them come forward. If fewer than expected come up I'd imagine the dev's to ban alot of accounts, some of them being false positives.
my suggestion is , once the exploit is fixed, open up the game again and extend this window of opportunity for weeks or up to a month. not sure what the cons are to this idea. any ideas?
Not really clear about the whole thing except that the exploit doubled money. if there are logs of doubling of money on some grand scale, then catching the perpetrators wouldn't be that difficult. but since there is a window of oppotunity, it doesn't seem like it is that easy. i'm still confused to be honest.
