Use your correct name.
Nicknames are acceptable, but names that no one knows you are not acceptable.
Some special names cannot be used.
Such as: cute fairy, beautiful fairy, smart boy etc. No name that hurts religious feelings can be used. Names that are not human names cannot be used.
No unreadable characters can be used for your name, but you can use the number at the end of the name if someone has already taken the name.
