You're now able to declare in the config the duration that the player gets banned for after they reach 0 hearts! The following are key letters you can use:

h or H - Hours
d or D - Days
w or W - Weeks
m or M - Months

You can also combine them like this: "1h2d3w4m" or "1h 2d 3w 4m"

Leaving the value blank in the config will make it so the player gets permanently banned.
