Reddit user commityoursudoku ran graphical analyses on this user's replays and has some interesting things to say about sayonara-bye/DH. Here's what he posted:

Hey everyone, ever since I've seen dh's skill skyrocketing nonstop, I can't help but look into his plays. This is just to raise a little awareness of the game's "anti-cheat" and how it needs to be changed.I wanted to post here to get more discussion going and also to get commityoursudoku's work out here as well. Keep it civil and discuss the facts he presented please.
I'm not going to throw accusations without showing any reason why, so here's what I've looked into.
First I compared dh's DTHD play with SnowWhite's play on Luminous. http://puu.sh/a0vt5/23c15abd40.jpg
Small translation first: Using dh's side -
Notes Hit Early: 298 Notes Hit Late: 378 Miss Reason: Hit too early: 0 Hit too late: 0 Aim: 0 Slider Break: 0 Key hit stats: Left-click: 638 Right-click: 88
SnowWhite only missed 4 times near the end, but other than that it was a perfect play. On the other hand dragonhuman played a bit too perfectly and I think I'm right about it, he hits his notes later despite it being DT.
SnowWhite's ms skips are not as tight as dragonhuman's, and SnowWhite played perfectly, though it may look more human on SW's side, I'm still a little skeptical about it.
This was played by a bot with 5 intentional misses and set with higher ms offsets and less frequent/ more gradual ms shifts (in the 20ms range), though this is not reliable because it was used alongside osu's auto pilot: http://puu.sh/a0wvg/141d707301.png
Before I go any further, the anti-cheat is essentially a data packet sent over to the osu! server after a score submits, and all it does is show what processes you were running. You can essentially bypass this by renaming your process and putting it somewhere where another program would normally run from and use a file pumper to add empty data to said process for it to take more memory, thus making it look like a legit program rather than some cheat. Kriers talked about this on his ask.fm, though his account is deactivated, hopefully someone can vouch here.
Another suspicious play is dh's DTHD play on this map on Extra diff: https://osu.ppy.sh/b/313621
http://puu.sh/a0tZR/b6aff00b3d.png
His offsets are very far apart and his 100s are made randomly (ei. in the middle of a stream there'd be a 100 but then followed by a stream of 300s).
I've noticed a pattern in his other replays until his more recent plays, most of his note hits are hit late.
Here are some more examples, this time using one of Cookiezi's DT score on Bloody Night and dh's play on the same map https://osu.ppy.sh/b/143989&m=0:
Cookiezi: http://puu.sh/a0yoT/b2ab7d7f29.png dh: http://puu.sh/a0yz7/691d18c3b2.png
As you can see, dh's ms jumps are bigger than Cookiezi's making his unstable rate believable. His hits here are also made late, but you can see the early/late almost equalizing here.
This is another replay proving my point about his hits being late. http://puu.sh/a0AJw/3e78b2ed81.png https://osu.ppy.sh/s/90419
Though this pattern was broken when I tested his more recent ranks where his hits are done earlier. There's no late/early variation in between replays, that much I can say. But his ms jumps and quirks are still very questionable:

Moderators, please do not delete this post. This is only for the sake of discussion. I've stated my opinion and have shown the facts above.
If dh is indeed legit, then I apologize.
