Hey there Gaeul.
In regards to your question.
1. All bans remain active for 1 year once the ban period ends so all active bans are the same.
2. If you have 2 active ban the next ban will be at the staff member’s discretion. If you have 3 active bans that is when the 4 is 1 month due to history.
3. No only active ban are counted for a permanent ban due to history bsns so you could have 5 inactive bans but only 1 active so that would be at the staff member’s discretion.
