I was running around Hellfire around lvl 61-62 with my 4x Shaman team when someone messages me "REPORTED!". I replied back with the standard "k" response. He messaged me again calling me a cheater and a bunch of other fun and insightful stuff. After a few minutes of responding "k", I look at what guild he's in and amazingly he's in the same guild as my main.

So, I log over to my main and put a message in guild chat...

[Guild] Hey XXX, can you stop wasting your time reporting my shaman?

I had like 4 people go "???", ">.>" and "huh?".

He was like ... "That was you?!!?!?"

Me ... "About that cheater comment and everything following that ... "

Him ... "Oh, yeah, sorry about that..."
