Psychologically, I perceived that DragonSlots had some shitty loopholes in his contest which he communicated with the rise as the contest manager. The rise seeing the loophole decided to benefit from it by applying to contest in a contest he was managing. There might be cockroach in the cupboard of both.
No facts, no allegations, just psychology playing here. I might be 100% wrong.
The biggest loophole on the contest is obviously the lack of participants. There’s only 1 entry with low multiplier so posting any entry can get a guaranteed prize that’s why the manager is so eager to join.
On the casino side, probably they are saving some bucks given that they are already paying the manager to handle the contest while his participation can result to paying him more instead to other players or they can save some money if no participants joined.
One is trying to get extra bucks and the other party wants to save some.
