Please add a /ignore <username> command to chat

The only other MMORPG I have been involved with was Everquest. IT had chat commands that limited whose comments would show up in game. Great to keep chat confined to specific groups.
I think this would be a huge addition to Zwift. The spam from the large group rides is annoying and too often contains juvenile comments. The ability to quickly type in /ignore <insert obnoxious rider/runnner here> and not see their comments ever again would be great.
