What you're describing is clearly against our community guidelines and the member should be reported.

There's nothing about the ability to be in multiple rooms at the same time that makes harassment significantly easier than just following the user from room to room in the old system. Sure, it took the harasser a little more work, but it still occasionally occurred. Harassment is harassment, and we don't tolerate it in our community.

Report it, and we will look into the matter further.
