if you can provide me with a snippet of code that has the possibility of producing random withdrawals then i can see about tesing it in running code for you.
How can someone give you the source code for the ponzi site? Well, may ThorSWO can - ask him.
Why does it even matter what the specific piece of code is and how it does this? It's clear the site has defrauded many users through misrepresentation and outright theft (no explanation yet for the missing 37000 KHS). No amount of shilling is going to change that, even if you try to disguise it as a "concern".
