Who to talk to about a impersonating problem?

Trolling me won’t work and no need to beltile me. I’ve been told by blizzard years ago when asking about the differce between blizzard name vs creating one. They told me by picking blizzard generate there can be only one. I’ve seen many cases of this on forums and what has been said about the problem.

Who told you can talk in an hostile manner to people? Last I check this is against the rules.
