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.
