Back a few months a go a was playing my theory crafted Morphing Jar deck. I was playing on Dueling Book and was joining anyone who's ruleset allowed me. One day I dueled the most toxic and annoying player to have ever existed. I joined his game as it was a non extra deck setting. I wanted to see how I would fair against something I would assume has no negates. So I finally get the perfect hand to ftk him. So I go with my play expected some salt but a begrudging accept of defeat.
But of course he had no honor. As soon as I tell him to discard his final set he starts spamming chat with stuff like "You can't win like that". "Ducking meta trash" etcetera. So he does the typical tactic of not accepting his L while I request a judge. Of course he says shit like "I will stay in this duel as long as I need to." Lucky for me that manchild has no patience and he leaves shortly.
Moral of the story be nice and have patience.
