He was active and quite helpful but after the last creditors' meeting (when it was officially announced that any surplus will go to shareholders) he deleted all his posts in the mtgoxinsolvency reddit. He claimed it was because of abuse and death threats. I don't doubt that the threats played a part in his decision but I also think that the deleting of his reddit history is an attempt to get rid off of anything that might be used against him in future lawsuits.
Also, he never went as far as claiming that he'd distribute anything he gets to creditors. He's always been quite vague about it and never answered directly when asked about it.
