I love these one sided stories and they play the role of the victim, the fact is you did something bad you got collared by a GM for it. Claiming you have no idea what you did doesn't really fly as the GM would of gone through logs to confirm the report and no they not gonna tell you what was said to protect the identity of the person that put in the report as it would be pretty easy for you to figure it out.

You got slapped on the wrist move on.
