to be honest, I can only think of a few instances where this would be useful. If someone is perma-banned or has been banned for a long time and you want to be nosy and don't feel like going through the ban list, I can sort of see this being of some use. Otherwise, you can, as I said, just look in the banlist for details. I don't know.
also I enjoyed the totally legit screenshot haha.
