Hope there is a feature to ban or time out live chat with long text or repeated spam in short time.
Eg. timeout chat that exceed a certain word limit(no. of character decided by user) like 200 chara out of the 255 limit. If spam exceed 200 chara auto ban or timeout
also hope have feature to ban or time out spam that spam multiple chats in short time like 5 message in less than 5secs.
