^Guys, he isn't really talking about broken replays (those are often bugs), he's talking about scores that either involve cheating, or involve unrealistic spinning .
Okay, let's see...
Ootsuki Kenji Hitotoshite Jiku Ga Bureteiru [Easy]
Just watch the #1 replay, not to mention look at the scores. #2 and below already have insane spinner bonuses, BUT they're humanly possible (just really, really difficult). Now, #1 got 40K or so more of spin bonuses (not to mention #2 SS'd it, he got 2 100's, and both weren't using any mods), not to mention the replay comes up with around 112K when his score is 190K.
Suara - Musouka [Easy]
So like, the same thing and all. Now, people below him used mods, for one. He didn't. Okay, he did better accuracy-wise, but 260K to 247K and below is a pretty decent margin on Easy, and again, the people below #1 got insane spin bonuses (like, 20K above me in score worth, even with the same or less multiplier and more 100s...but I got 6th this time. XD).
Again, his replay comes waaaaaay off by the end. It shows him spinning a lot slower than he should have in order to get those insane bonuses. >_>;
Either way, I think those scores are overspun. You can check for yourself if you want. =P
EDIT: Oh, it's the same guy. And what I was getting at was how insane his bonuses were, even though the replays showed him spinning at the speed I usually spin at. Yeah really.
EDIT2:
Allegro Cantabile (Easy)-
Okay, this guy didn't do well, with no mods, and got... #1. People below him used mods, did much better, ect. Yet, he got #1, yet he didn't get good scores (100: 10 | 50: 5, which isn't good at all on this map, especially without mods). This doesn't normally happen, so I think something's wonky here. XP
