Who do u think are the worst black flags

In my mangago discord server; someone was trying to tell me Jaekyung (horse face from jinx) isn't the worst top ever. Cuz he's a red flag but not black. But like idk; I don't actually read a lot of Bl with super red flag tops or "black flags". Who would u guys say are some of the most famous "black flags" cuz like for me, Jaekyung is really up there. Did we forget how we fucked Dan blindfolded in front of that pink haired dude without Dan's consent? （πーπ）
Also he's just abusive; is he not???

Like I know he's probably not the worst; but just off the top of my head I don't think I can name that many black flags.

Also if u wanna join the mangago-ers discord server here's a link lol
