"Real" Ducking / Crouching allowed or not?

[Haco]

Hi, quick question to make it clear:

Is ducking/crouching whatever you call it allowed  -  as long as NOT using the mousewheel?
To make it clear - Iam talking about this:

So - I'm still waiting for a clear admin answer.

There was once a anti-duck plugin installed - but got removed again. Obviously, because ducking is great. Make ducking great again! YES WE WILL
