4. Evidence/full screenshots

 

This one looks to me as if the player was lagging out. He wasn't swinging at anyone, therefore it tells me that he was a victim of lag. Closing for lack of evidence, sorry.

 

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
