What the hell is this z8games?! Tell me?!

This is the message I put into a support ticket. Please read this. I THINK THIS IS A SPEED GLITCH AND I HAVE NO IDEA HOW I HAPPENED! I DO NOT HACK!!! I REPEAT! I DO NOT HACK!!!!!!


What the heck is this? Before I begin, I will tell you that I DID NOT hack this. I am completely bewildered as to how this happened, and I did not know that this even occurred until my clan mates asked me to watch the replay. This is the full explanation of what happened (I am sure people are reporting me for something that was completely not my fault):

I entered the Fortress team death match as normal, without any issues. I used my MP5-Advanced and began shooting at the black list side. I did not notice anything in particular. The gameplay was absolutely normal and I did not notice anything that was even the slightest hint out of the ordinary. I began to wonder if something was wrong when it appeared I was not taking any damage at all and I could walk up right to the other base without taking any hp damage. My gameplay was still smooth and nothing seemed out of the ordinary. People started to accuse me of using a "speed" hack. I didn't understand what they were saying. I was just playing ordinarily, without any sort of strange factors besides, again, the seeming lack of damage. At this point I began to realize the opponents were not shooting at me. Confused, I asked some of my clan mates to join in to see if there was anything wrong. They told me I was flying around. I assumed it was some sort of lag and I just brushed their comments off, saying all I was doing was "rushing, spraying, and picking up guns." The complaints continued and several players announced they would report me for "speed hacking." I still did not get why everyone was getting so excited. I didn't notice ANYTHING wrong at all! I thought all the comments were just ordinary complaints from people who died when the game finished. My clan mates told me to watch the replay. I saved the replay and watched it, and I was completely BLOWN AWAY. I was watching myself spin at insane speeds and flying around like some sort of hack, but I had no clue what the hell that was. I was just playing normally in the team death match, and the replay shows up like THIS?! One of my clan mates said the thing was a speed glitch. Could you please shed some light onto this? I hope you will not announce me as a hacker. I did nothing wrong, and I would not sacrifice all I have put into my account for a hack. It would not make any sense at all. I am sure you will understand what I am saying. I uploaded my replay for your convenience:

Could you tell me what the hell this is? I have never seen a glitch ANYTHING like this! I would appreciate you seeing this as a glitch instead of a hack. Check my player account. I refuse to use any hacks of any sort, and I will never hack. Thank you for looking at this. I hope you will treat my case fairly and not as a hacker account. Thanks.
