I'm pretty sure that's neither the first nor longest time he did itThough he did it for a number of days after March 18 2018, I don't believe he ever did it before then because I've been checking regularly. Note that for Worst Nodes of the Year you only need to check once a year or so whenever there's a "blocker" (i.e. a huge negative reputation node written by someone else) on the Worst Nodes list. That is why it is such a rare feat: you need a full year without some random troll posting an absolute shocker. The last such shocker was Re^4: Canonization Without Representation (rep:-27) by trippledubs - which disappeared from Worst Nodes of the Year on March 18 2018.
