Since you have explicitly asked for advice I will provide some.
  1. Never, and I mean never, put your advice into public/group/alliance chat. That will always be public shaming. Praise someone in public. Punish in private. Either privately whisper the other player or send him a mail later.
  2. Always give advice when you and the other person are calm. Attempting to give advice during the "heat of the moment" when your and their stress and frustration are running high will either result you in framing your words very badly and/or having your words received very badly.
