An account deletion is the most serious form of punishment that occurs if the player has severely violated the Tibia Rules on multiple occasions or if the account have been detected using unofficial software to play. Deletions seldom occur instantly, but accounts are banished until deletion while an open investigation is still ongoing. The player may complain for the typical period of seven days. If the banishment still stands after these seven days, the account will be deleted.

Accounts caught using unofficial software by the detection tool may be deleted outright, though the criteria used in determining the punishment is not known.

Another occurrence of account deletions is possible. First, a player will be banished until deletion if his premium time payment is canceled after he has activated it. The account will remain this way until it is repaid. If too many charge backs occur, the account may be deleted permanently.
