someone stalking my girlfriend and reporting her the whole time to get a ban he did already over 100´s accounts
If your girlfriend is not breaking IMVU's terms of service, then reporting her will not do anything. You can stick to private chats and set your status to "do not disturb" mode. He'll get bored after a few days.
That, or park her avatar AFK in a dozen random rooms to distract him. Let him waste his time trying to pixel fuck a brick wall.
