Quoted from chooch:
I heard it last night and there was not anything said that would make Robert threaten him to take it down. He did a lot of trash talking on Steve Bowden for not answering his question when Steve answered other peoples so I bet that is why he took it down. I don't think Steve really deserved the stuff that was said and he is just a victim of circumstance on Robert's sinking titanic.
Or a victim of circumstance on Robert choosing to take them onto Kaneda's show. Either way.
