It would be unethical to simply take someones hard work and put it on sale just because he/she hasn't logged in for a while... If the owner wants a break from tibia or any other reason to not play.. don't you think is OK to just take someones char just because he/she didnt play. The owner has every right to sell/delete/give his char at any point he/she chooses.
How would you feel if one day you decided to login back on the ot you played a few months ago on your high level char and you realise admin without your permission took it and sold it..?
Characters not logged for the last 40 days can be put on the list below. If you do not want your character to be bought, just log it in the game! Hurry up because if the character is auctioned, you will not be able to retrieve it.
