Does crouching make it harder for Roadhog's hook to hit you?

So, there have been quite a few questions revolving around Roadhog recently. To save space on the title, the real question is:

Can heroes crouch to avoid Roadhog's hook?

Considering a perfectly accurate Roadhog, can I dodge the hook without moving? I have seen in a gfycat posted on Reddit that a Zenyatta crouched under the hook, saving himself from a face full of Rolin's man meat. Is this possible for the whole cast, or was it a fluke thing?

Edit: Here's the GFY

No.

Crouching will not help you a tiny bit, as the hit-box of the hook is enormously huge, much bigger than what Hanzo's is, for example compared to the model (as he's complained to have really big hitbox arrows).

Well not that much to actually care about. It does reduce the hitbox, but if the Roadhog against you is anything above 250 raiting, then he'll be aiming at least somewhat at your height, and as show bellow this wont save you.

Check this video at 4:00 for more details. Basically the hook is actually twice as large as the model shows. Soldier is definitely crouching and the shooter is aiming quite high, yet he got hooked.

The hook and the animation have a weird mechanic, and that's why many people were dragged trough walls and across the map before people got teleported to the point where they got hooked. When you hit the button to hook someone, and the croshair is on the target, this doesn't mean that you'll hook them. Nor is the case when the hook starts to fly towards the target. The hit scan actually triggers about half way into the throwing animation. Roadhog kind of points to his target, while throwing, this is the exact moment when he'll hit-scan and hook you. And that's what I'm talking about. (1 minute into the video)

It depends on where Roadhog actually throw his hook. I personnally have the tendancy to shoot higher than lower because more people jump than crouch in a fray.

So if I play Roadhog and the enemy crouches, there's a possibility that my hook misses. (Because your hitbox becomes less high).

In the case of the video linked, I don't even think the crouch really helped Zenyatta there. The hook seems like it was missed to the right of Zenyatta in the first place. We would have to see Roadhog's perspective to completly tell.

In short, yes crouching does help but so little that it probably won't matter. You have a lot more chances to just juke him by rapidly switching directions than trying to crouch.

A perfectly accurate Roadhog would be aiming at the primary mass of the target. Crouching does not move the hero's hitbox, only shrinks it a bit. As a result, in most cases, the Roadhog will still hook whoever was crouching. The exception is if the Roadhog aimed more upwards, meaning that the hook's hitbox will pass over the crouching target and miss.

Roadhog's hook has a reputation for being very wonky, so it's possible that the Roadhog missed his hook to begin with, or it could be one of those weird cases where it looks like it should have hit but didn't. Based on the gif you supplied, it looks like the Roadhog aimed too far to his right - the crouching had nothing to do with the the dodge.
