As far as I know, he posted some picture (I was not here, didn't see it). He didn't have to say anything, his words were expressed by the picture - he used it knowingly. And Jim said what he said, he is THE BOSS here, he decides, he rules this place. If he finds it horrible, then bye bye. And if Jim warns that any further comment will result in sending member's details onto the police, then it is OBVIOUS it is extremely serious. I still fail to see your point in wanting him back.
