I got banned due cheating?

(I couldn't find the right section where to post this)

- So like 2 days ago some guy asked me where did I get my Tabard of Exploler (I am 29 twink). I told him that I wont tell. Well he told me that he will make a ticket to GM... I was like sure, go for it whatever. And now my account is suspended.

And this is how I managed to get my tabard.
I was chilling in Dalaran. I saw a drake near Dalaran flight master, well I tested if I can get in and ofcourse it worked. Well I got idea that I go explore Northend for the tabard...

The reason of my ban is cheating, so maybe GM think that I used flyhack or something. But no, I managed to get that because sever bug.
I'm in holiday and its perfect time to play and now I'm banned because some noob!

Looking forward to see comments.

You're banned because you abused a bug, which you clearly even admit to.
The only one to blame here is you, not some noob (unless the "some noob" you meant was yourself).
