Tournament:Glitch 7 - Minus World
Super Smash Bros. Ultimate singles
Super Smash Bros. Ultimate doubles
A week before the tournament started, PGStats determined that Glitch 7 would be a S-Tier tournament due to the number of currently-ranked PGRU players attending the tournament. However, Stroder would disqualify himself from the tournament, directly affecting Glitch 7's score and dropping it below the S-Tier threshold of 2,400 points. As a result, PGStats announced that Glitch 7 would be demoted into an A-Tier. This decision, which some have dubbed as "GlitchGate," caused some controversy, with people pointing out how MomoCon 2019 kept its S-Tier status even after having over 50 disqualifications, which would have also lowered it into an A-Tier.
In response to the controversy, PracticalTAS explained that counting disqualifications for normal entrants was extremely difficult and potentially inaccurate due to how many are listed as 0-2 instead. Furthermore, suar linked and agreed to a post where another player stated that tier values were simply a title, and that how much the tournament weighted was more important. 
This event is likely the reason behind the following Spring 2020 PGRU season adding a 1-DQ buffer to S-tier tournaments, along with counting disqualifications in free-to-enter tournaments.
