BetterAntiSpam creates the quarantine role automatically if one isn't set.
If strip_roles is on, the member's other roles are saved before removal so they can be restored later.
If the quarantine role or the member's saved roles carry risky permissions, BetterAntiSpam shows a warning and asks for confirmation before proceeding.
remove without reapply_roles only removes the quarantine role. With reapply_roles, BetterAntiSpam restores the member's previously saved roles and asks for confirmation first if any of them look risky.
A case is created for each quarantine action and logged to the quarantine log category if configured.
The quarantine role is shared with /antispam settings, /antinuke settings, and /antiraid settings when quarantine is selected as their punishment.
