1. Your ingame name: andrewswj
2. The offender's exact ingame name: BooIsBae
3. A description of what rule they broke/how they broke it: Hacking (Fly)?
4. Evidence/full screenshots:

 

I think this was more graphical than hacks, if the player was changeing height then I would say hacks but as is I do think it was just a graphical bug

 

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,
