Harrasment & Malicious Intent

[Jojoya]

For regular players a name means very little.
For Streamers or other content creators, Their character names are often associated with their brand.

If someone just took it to annoy them by never actually using the character, that's fine. Happens to all streamers who play MMOs.
The problem is when someone uses that name to impersonate you.
That can do irreparable damage to people with a public image, like a streamer.

Doing or saying something while pretending to be someone else can cause loss of sponsorships, channel demonetizations etc.

Losing your name to a normal player is not the problem.
Impersonation and attempted coercion are literal crimes.

It doesn't matter if someone is using a name as their brand. They do not own the name within the game. Names are first come, first serve.

Someone having the same name does not mean they are attempting to impersonate another person. To be impersonating, they would have to be telling others that they are the other person.
