I want to believe.
But i can't, too hard to understand for me.
The easiest one according to my understanding is:
When a block solved and (if it really being) "redirected" to another address, I'm sure our address will be at the first place and we can find the trails from blockchain. And if it really happen, that's the time we can make a judge to the machine owner.
I still believe in ck's statement and i hope he's right.
If the hashrate is directed at one address it is impossible to redirect a found block to another address.
Cheers.
ps.
we have a growing hash rate

"hashrate1m": "5.39P"
