Oh yeah, I belive this person you claim to know doesn't actually exist. Bungie nor playstation will ban you for this. You are simply leaving a game, it's not doing anything other then that. Bungie and playstation would announce they are banning players for this if that was the truth & they haven't, only players with modded consoles which they've already announced and it's funny how your friend is the only person in the world who seems to have been banned for this. It's total bullshit.
