So the way I put it: Slush gtfo of our merge

Of course I can cheat! Any pool operator can cheat. I can not publish some merged mined blocks for namecoin and nobody will notice, as any other merged mining pool can do. So why do you have problem with me? I think that I already prove that I'm not a scammer, by running pool for longer time ever.
My issue is: That hashrate has no point in being there. If people want merged mining they go where it is offered. Unofficial testing is just a convenient way of risk reduction (for you).
The thing was announced way in advance so there was plenty of time to test on testnet.
Stealing may not be the right term, but we (the people mining at official merged pools) would get more nmc if it weren't for you, even if you pay out the earning to your miners.
