To add to what was written above, the MEMBER BAN system can also set a time expiration for bans. ie; an admin bans user for "1 week." After 1 week, the ban automatically gets removed, and the account is returned to the way it was before it was banned. Think of it as "probation."
Some forum admins just like to ban problem users for 1 year, but most set the ban period to, "Never. Permanent Ban." See attached screenshot.
