if the emote prefix is going to auto generated then it would be helpful if there's a guideline to the format in which it might be generated like "6 characters which will include at least first 4 letters of username" or something like that so that we can get a simple and more apt prefix. This will give smaller streamers more suitable emote names which will boost emote usage and overall improve the viewer experience and help streamers in improving their streams and in reaching the partner status. Its a win-win situation for both Twitch and its streamers.
