Closed excessive punishment for "account sharing"

Character Name: cleric1534, bloodless

Last thing you did: haven't played in a while

Why do you think you got banned?: i got banned for security reasons, and on my appeal i admitted to opening an account for my brother, i didn't realize at the time that it was forbidden. I got perma banned and so did my brother.

Ban message when attempting to log in: ID had been deleted or banned

i admitted to opening an account for my brother when he joined because he couldn't speak english well, he changed the password and didn't share the details with me, and then played on that account on his own for 4 years.

according to the terms and conditions found here: https://royals.ms/forum/threads/mapleroyals-game-terms-conditions.86769/

the default punishment for "Account sharing" is a 30 day ban, unless it is one of the cases specified in the appendix:

1. Using power-levelling services;
2. Two or more people taking turns in levelling up a character (ie: training);
3. Logging onto someone else's character in order to leech your own;
   
4. Removing items from or deleting someone else's character;
5. Giving an account with a high-levelled character on it to someone else;
6. Committing a bannable offence (other than just account sharing) on someone else's account;
7. Wasting staff time by lying about the account sharing;
8. Sharing your account details with multiple people.

none of which i did.

according to the things i listed above, the fitting punishment would be a 30 day ban, as it's my first offense and isn't a severe abuse.
i'd appreciate it if you turned the perma ban into a 30 day ban, or explain why this case counts as "severe abuse".

thanks in advance
