Ban the accounts that are selling 500k dilgeles to people. Ban based on IP. There are too many security flaws in ToS to protect it from a legitimate hacker, if you think these Brazilian kids exploiting a flaw in a payment system are some kind of untraceable evil geniuses you’re out of your mind. Also, I don’t know how this Brazilian payment system loop works, but unless it’s completely ■■■■■■ up ■■■■ concocted in BIZZARO WORLD, you will need a legitimate bank account to start the transaction even if you never complete it - so they can track all of your secondary accounts based on the bank info you used. Again, if you think some Brazilian kids have a bunch of different bank accounts you’re out of your mind.
I would say the exploit is likely not very widespread, and also never made anyone that much silver to begin with considering the market was flooded with tokens from day 1 - and no, it wasn’t flooded with exploit tokens immediately. Lots of people are more than happy to sell tokens for virtually nothing, even if the cash to silver ratio is really poor. You need no more proof of this than the fact that people buy silver from bots at ludicrous prices; far more will sell tokens for their silver since they know that’s safer.
In addition, it isn’t an “infinite silver” exploit. It can only make as much silver as you can get off the market from selling tokens, which I doubt is that much since most people in the early access at the moment already have a token, and those that don’t only need to buy one.
This is so far from an end of the world scenario. kToS had legitimate exploits that generated MASSIVE amounts of silver and completely ■■■■■■ up the economy - the players in question were banned and there was no wipe. That was a much bigger problem and kToS recovered from it. Stop the doomsaying; I suspect a lot of it is overly dramatized acting because you want a wipe so that you can reroll on even footing with others because you ■■■■■■ up your character somehow and now you’ll never fulfill your dreams of being #1 on the server or whatever.
