big point here; even if they decide to pay out, their decisions in handling this entire matter were questionable at best, announcing their site as the subject of this thread was probably the biggest mistake, this is a lose-lose situation for them now.
Don't get me wrong, the owners of this site are giant morons, acting unimaginably unprofessional. They've basically gone all dadice, and made themselves toxic to anyone with a few braincells after the way they are acting now.
But after seeing the nature of the exploit, it's obvious why you're acting like you are. You didn't exploit it, because you didn't think you could get away with it for long enough to make any money. And you didn't mention the site name, not out of fear of shaming them but because you knew the exploit was easy to find and didn't want anyone to give it to them for free.

youre free to think what you want; but i didnt try and exploit it in any way after seeing it. i honestly tried to help the admin out but he dissuaded me from doing so. anyways, this has escalated into a rather interesting event.
