I get what you are doing, but I want to point out all one word comments are not useless.

I stream on DLive and have developed chat commands which play sounds to my stream when a viewer uses them. DLive is a streaming platform built on top of the STEEM blockchain and thus, the "comments" are what the chat is built out of. Look at this picture of user's using these chat commands to interact with the stream. Their comments absolutely had a use.
