For what it's worth, Jones did have to spend several years consistently abusing the discovery process (across multiple cases before this same judge) before it got to this point. It's not like he made one or two innocent mistakes and got slammed down for it. It escalated through a whole bunch of different penalties that didn't fix the misbehavior before this default judgement happened.
