Dooglus is a reputed member of this forum.
He found a bug in your site, whether he is a competitor or not, he found a bug which could have lost you a few btc. If the same system was there for "Free play" too, then many would have spotted it and if you were unlucky could have cost you losses.
He has helped a lot of sites recently. like SD.
And there is no use paying for a review unless it is for a very reputed site which will affect the traffic considerable, which I doubt is the case.
He found a bug, took advantage of it and only then told about it.
you sound mad that your bug was exploited, as if anyone isnt going to when they find it
The guy has been totally discredited. He simply didn't want to pay for me reporting the bug, so he made excuses not to.
I didn't attempt to withdraw my winnings - I only exploited it to prove that it was possible, but left my "winnings" on the site.
Anyway, it's all just water under the fridge at this stage.
