Please be patient while @Unknownrider reviews the evidence.

 

Doesn't look like oink_oink_ is the only one hacking in this video then.

 

From the first video, Oink was swinging a lot trying to hit you, but none of those hits landed onto of course the one that actually killed you. If Oink was actually using a hacked client, who would have killed you with hit number 1, so that part will be dismissed. As well for the other user in the video, him and Oink clashed swords with each other once, then Oink hit him a second time for the kill. Nothing suspicious there.

For the second video, you were sprinting after Oink so there were particles coming off of your feet same as Oink's were. That being said it would be easy for him to pinpoint your location with a simple f5 tap. So we can go ahead and dismiss that as well.

No evidence of hacking.
