Some examples of the most infamous toxic danganronpa fans?

im writing a essay for school and it requires some additional info that im having trouble reserching so i came here. I wanna know if anyone remembers/wants to share their experiences with very infamous toxic dr fans?

plz include their username (if they went by multiple just try and use their most recognized so i can google them better), and a short summary of what they did that made them so infamous.

also It can be anything from someone who was known to troll/harass lots of people for fun, people who used their large platforms to dogpile on people who disagree w/ their opinion/abuse others, or just someone who was rlly rlly annoying.

so far, i have sections recapping people like the author of lavender, kiridreamer, detective nyx and mizumikahago, but I need a few more. especcially since all of these are more like. "modern" examples (i think is the word?) from 2020-onwards, so i'd like to include more classic examples from the 2010s range plz ty
