Is this aloud?

I was arguing a bit aloud, and someone showed my in game name which totally invaded my privacy, and i'm an active name buyer so this shouldn't be aloud. But my question is, can someone do this to me?

Did this happen anywhere on sythe?
We can't really do anything if it's just ingame I'm afraid

 

A sythe user posted this on a forum. It's not comfortable for me to know that everyone in sythe has access to my username. Can you do anything about this?
