While i was down stairs in my house this happend on my pc.. i was standing with chat open in the lobby of a server where a play often. and then this happend and a staff member recorded my and was thinking that i use killaura (hack) but i dont use that on that server and at servers at all! so i was banned but i tought maybe this was a minecraft bug or glitch so i reported it to here. I hope you guys can help my because its my favorite minecraft server.
Thanks and Kind regards,
Alvin Vrolijk from the Netherlands.
(I included proof of myself doing strange things with my head in this post, and it happend in minecraft version 1.11.2 with optifine enabled)
