Can the minimum freeroll reward reduce so much that it becomes 25% of the full amount? -> 8 satoshi instead of 31?
That was just a tempory adjustment, it's back to 33.5% now.
in the next branch of the forum, the user proved that the results of the lottery are wrong, they just gagged him, paying 2.5 million Satoshi.
I would not be surprised if in this gambling they twist the results in the same way.
Yet again you are totally wrong. The lottery has always been drawn on the 6th Bitcoin block in the future. We changed that to 12 blocks in the future but the change didn't stick. That only caused a display error for which we paid a bug bounty to the person that spotted it. We are no more able to 'twist' the hash of the 6th block than the 12th.
I would be surprised if you ever got any facts right.
