I feel like they should record how long a person has a red bar for. If the person red bars for a long period of time, they should be notified that due to poor connect that they'll be removed from Crucible after their next game until their connection improves. Instantly banning red bars is a great way of banning someone who's Internet happens to have hiccuped. And OP you're does it too, everyone's Internet does in this game. The matter of being able to solve this probably would be through identifying who those are that are consistently red baring.
