Block Finder BONUS
The block finder doesn't have to pay mining fees! There is no reason to pay bonuses to the finder of the block, because to make up for it other miners will get fewer rewards. While finding a block is not an achievement (it's probability) it is a good deal for the pool and everyone involved, so you don't have to pay any mining fees.
I don't think this is true, I solo mine 2 blocks @ 100 per block and my unconfirmed amount is 197, so it did charge mining fees.
