"Discord has had problems with hostile behavior and abuse within chats, with some communities of chat servers being "raided" (the taking over of a server by a large number of users) by other communities. This includes flooding with controversial topics related to race, religion, politics, and pornography. Discord has stated that it has plans to implement changes that would "rid the platform of the issue" "
It looks as if "Discord" might be a good name.
