To summarise, in my opinion, lack of clear rules should be judged more (but not entirely) in favour of participants. FJ should apologise and look to settle the matter by paying out at least according to the table, so:
4-10: 3 btc total: ~0.43 each
11-30: 3 btc total: 0.15 each
But you should give FJ right to reject very low-quality vids (if there are such at all).
Hopefully that would settle it.
The only and simple way to solve this problem are pay the amount which pawel7777 mentioned.
fj must realized current -4 negative reputation in their account will affected to the casino.
pay them and case closed because fj has a good intention . but if they refused / ignored i think they deserve more negative numbers?
