"This video is private"

 

Oh thats weird, let me have a look at it

 

Here it is:

 

This video is 8minutes long, do you have a specific time in the video with the evidence?

 

Yes, at around 8:32 is when it happens, but start watching around 8:25.

 

If you look closely, he does take kb In the second hit. The first hit he's standing on a slab which can sometimes cause the player to not take knockback.
I'm going to say this is lack of evidence, please feel free to report again in the future.

 

Thank you for the report.
Unfortunately the evidence provided is insufficient.
Should you gain more evidence in the future, do not hesitate to report this player(s) again.

Kind regards,
The Staff
