> you can aim the fee going to C by only sharing the transaction with C and just wait till C gets the block

If that's technically possible then that seems to be an easy way to launder money. You should probably split up your transaction and send your coins in a circle to obfuscate it.

the money launder does not make sense to me - everybody knows who mined the block and everybody knows where the fee goes... So it is perhaps not tracked by current systems but it can be tracked.
