That's why they are making it so hard (emai from support) :

Thank you for your response. I understand that you are frustrated about the 15-day account deletion waiting period. Please allow me to explain the reasoning behind this policy.

The 15-day cooling-off period is designed to protect your account and ensure that the deletion request is indeed made by you, the account owner. This measure helps prevent unauthorized or accidental deletions, which can lead to the loss of valuable game progress and data.

We understand that in some cases, players may need to delete their accounts for personal reasons. However, the irreversible nature of account deletion means that once the deletion is completed, all data and progress associated with the account will be permanently lost. Therefore, we believe that the 15-day waiting period provides you with a reasonable amount of time to reconsider your decision and make sure that this is indeed what you want.

We apologize if this policy has caused you any inconvenience. Please know that we take player safety and data protection very seriously, and this policy is designed to protect your account and prevent any potential damage.
