Sorry but.. 1. This should be your friend asking not you. 2. Bungie will not discuss restrictions to anyone more do to someone else other than the person action was taken against. 3. To put it bluntly... they were lagging and ruined game after game for others. These players reported your friend and Bungie investigated them. To get a 2 month ban they ignored a stand alone warning and another warning which came with a 2 week restriction. They need to sort out any internet issues and it below recommended internet speeds or having a high signal latency/ping. Next time Bungie has to step in the restriction will be permanent. Also be sure of your terminology... Suspensions... a time out for leaving matches too many times. Last 30min to a hour. Restrictions... Bungie removed the player from pvp for a time (first time 2 weeks, then 2 months then permanent) for ruining pvp matches for others mainly from lag. Ban... full removal from the game issued for cheating.
