I think the 1 BTC listing fee was waived for Aqua on Tidex.
I've had a bad feeling about the dev since the moment he first disappeared. When he reappeared and tried to pretend he had no idea that deleting his slack user name and his website would even be noticed, it did not ring true to me. I noticed some weird price manipulation action going on with Aqua at Tidex after the price initially plunged. It looked like someone was trying to pump the price up with lots of little buys at higher prices. I had a sense it was the dev doing it. Now it makes sense that he was trying to pump it up in order to maybe dump some of his remaining stash. Anyone can see that he has indeed moved most of his supply of Aqua that he always claimed to keep in his wallet.
Even with all this, there will probably be some that seek to defend him.
I noticed he got a cool reception when he reappeared on slack with his new "vessel" identity. Many seemed willing to give him the benefit of the doubt. I'll be amazed if he can recover from what we've witnessed today.
As I said before, the real sad thing is that he's colored the way many will perceive future projects based on his shady actions. I hope the powers that be move quickly to remove the privileges that were granted to him and that steps are taken to ensure he's not allowed to take advantage of the community again under a different guise.
