KOSing !emotes is not allowed, CT's are only allowed to restrict the use of emotes and give warning shots if T's emote after the command.
CT’s may only attack rebels as attacking anyone else is classed as a free attack or free kill. If you free-attack a T, it's courteous to take them to medic. If you freekill a T by accident, you can ask a staff member to revive the freekilled T. If this happens no further actions are required. If this is not possible. You must go to armoury or somewhere where out of the way to kill yourself - if not, you could either just be slain, or things could be taken further by admins.
CT's must try to find missing T's and not just let them get to LR. However, if a T decides to hide somewhere to purposefully delay the round whilst 2 T's have received "guaranteed LR", the missing / rebelling T is required to actively rebel and try to kill the CT's. Not doing so may result in a warning or slay from staff members.
Some spelling issues
Changed formatting slightly in OP.
When a CT has freekilled someone accidentally. A staff member should revive the freekilled T when possible. Try to avoid slaying CT's so the round can continue normally. Only when it happens on a constant basis or you decide that the freekill was not an accident should the CT be slain.
