It looks like maybe SpaceX has just publicly admitted (via NASA) that they have a debris problem. So much of a problem that they have set up a debris reporting hotline!! (I am sooo tempted to call it - but I'm sure they wouldn't answer any of my questions either)
I tried searching for this statement from NASA but the only source seems to be a screenshot of text on twitter (that a journalist sent me)
(...could it be a prank? That would be a *hilarious* prank)
