Bouncing Balls was explained away at the time as being Caps0ff's; C0 *was* doing some 68705s around that time. The only "AW dumpers" I know of are Guru and the DEMUL guys. And the existence of a 68705 dumper isn't what's being disputed; the bus factor of it is.
Look at the bright side: they did such a good job hiding that this was going on that they're going to have trouble proving any of it until they meet whatever conditions Japump has set and can release these dumps.
