Chat filter for duplicate characters
Due to the nature of bigger streamers chats, I think a chat filter is needed to automatically block messages which contain over 10+ of the exact same character and they should be blocked before they are seen in the chat.
It really is disturbing to have a large block of just the letter "g" to be thrown in the chat when trying to read. This has become really noticable in Ninja's streams with the large amount of people in his chat.
The same could be done with emotes, except possibly giving the streamer control over it due or having a higher trigger for the message to be blocked. Since in streams chat will often react with a large amount of emotes but they shouldn't be able to send a block of emotes in.
This would really help improve the chat experience and would be a simple solution to making it easier to interact with chat.
