Banishment
From TibiaWiki
If you have violated the Tibia Rules you will most likely get a banishment. Banishments can last seven, fifteen or thirty days, depending on the rule broken and previous banishments. The banishment makes you unable to log in to any character of your account and post in the forum. You can't bid on houses and you can't edit your character description.
If you think your banishment is unfair and it is imposed by a regular Gamemaster you can complain about it by using the complain function in your account page.
Apart from the regular banishment, there are other kinds of punishment on Tibia:
