TheAbsoluteMadLad's a cool guy. I enjoy playing with him, and against him! As Braun he's taught me much about Sec, and been fun to RP with. As antagonist he really prioritizes on telling a story over winning the round.
Martin Braun has served as Interim HoS a couple times, and did a great job coordinating Sec each time I was present to witness.
That's why I think you should whitelist him. I'm surprised he hadn't been already.
