Rule 5a) Account Trading or Sharing
An account should always be used by one person only. Only the person that created an account is allowed to use it. It is unfair towards other players if a group of several people shares one character e.g. to be online 24 hours a day. Moreover, you will be held responsible for everything that happens on your character. So if your brother violates a Tibia Rule with one of your characters while you are in the bathroom, you will have to deal with the punishment.
Sharing your account data with another person is not only against the rules, but also a high security risk for your account. It is actually one of the most wide-spread reasons why a player loses his account. What if you suddenly got into a serious argument with a person that you consider your friend and who you are sharing your account with? Or what if one of your friends suddenly decides that he would like to play your shared character alone and takes over your account before you can react? Account sharing is not worth the risk, which is why you should never do it. Besides, it can as well lead to an account punishment.
A regra existe, só o criador da account tem o direito de jogar nela, porém a questão do sharing é quase impossível de fiscalizar. Poderiam muito bem verificar o IP e configurações da máquina onde o char está sendo logado, mas algumas pessoas jogam em lugares diferentes, conheço vários que usam PC do serviço, da escola, da casa da namorada, LanHouse e etc, sem contar com os proxys que dificultam ainda mais essa verificação.
