Something you might want to do is add your name to your signature, similar to this:
OOG: Rotem
That way, people KNOW it's your OOG name. We've had a few other people with names that sounded IG play, and that usually helps straighten things out.

(For example, Liam Neary OOG, and Liam the Celt IG... two different people.)
Thank you for reading up on the policy before you posted, it's appreciated.
