why would hufflepuff/robinhood do this? instead of building up more profit, day after day, making new accounts so it's not obvious etc.etc. ?
Because Stunna has already noticed the problem, patched the bug, and declined his withdrawals at that point (though it is a bit too late).
Check the bolded part of Stunna's original post:
Since this up again.
Robinnhood = Hufflepuff. Both abusing the same exploit I posted about a couple of months ago.
Hufflepuff was paid out over 2.5k BTC over multiple accounts he used with this exploit. Can link the TXID's if need be since I'm not concerned about his privacy obviously. Robinnhood however was not paid out as when we patched the glitch we made it so anyone who did it could not withdraw in an attempt to recoup a small amount of our losses from the exploit. So instead he kept rolling wins in attempt to be funny with no ability to cash out.
Hope this clears things up.
And Primedice's bank roll was barely affected and the exploit is now 100% fixed. The exploit only affected the house & not players. This is another reason why we don't accept investments and advise others to be careful doing so! Unforeseeable stuff like this happens.
