Yep, it's basically market manipulation at this point with them not letting any large withdraws get processed. If you check the transactions list, there's barely any above 1k tokens let alone in the hundreds of thousands. I wonder what the end goal of this is, since if they wanted to dump their own tokens they've had plenty of time to do it already.
It couldn't have gone smoothly, could it?

The same address often appears there.
They even turned off the option to cancel withdrawals.
