They're spamming the order book to raise the lag time.
Why O why is there not a fee for putting an order into the book? Are they trying to replicate the stupidity of the NYSE trading bots?
Why oh why didn't I think of that? That's a really good idea. Fuck fees on actual trades... put the fee on the order making. I guess I can understand why Gox didn't take this route to begin with -- liquidity was necessary and only possible through more adoption and exposure. We have that now though. So yeah, hey Gox, change your plan thusly -- it'll even probably eliminate your lag problem.
