Sorry to hear that someone is impersonating you.
To everyone and the unregistered lurkers here: Don't trust anyone when they whisper you to 'borrow' a set/weapon or anything until you've confirmed.
More likely than not, the people who do this may very well be someone you know.
And noosy, I wouldn't be surprised if the culprit is in your guild by any chance.
Life beyond the binaries.
