Hacker In HC.

Your username: Xadidax
Username of accused:niplpod
Server he was on: HC
Screenshot/video of abuse: Below
Detailed description of abuse: He was glitching on purpose and used anti-knockback on HC while in sumo. He was also flying In the spleef session In HC.

 

I'd say this was lag but I can't really tell for sure.
For something like this, providing video proof would be better or screenshots of different positions he's in if he's flying around or just staying in one spot.

 

It's not lag. He did it twice, once spleef starts he moves around and stands still, after it's done, he moves again.
And you can see i screenshotted it 2 times. The 2nd shot would have him more down.

 

Alright. After looking at the screenshots a bit more, I have come to the conclusion that this is in fact hacking. Thanks for reporting.
