Spam checker settings apply globally across all workspaces. Teams with different spam tolerance requirements per workspace, such as stricter filtering for a high-spam region, have no way to configure this independently.
Admins should be able to configure separate spam checker instances with different thresholds for different workspaces, so each workspace can apply the spam filtering level appropriate to its context.
A single global spam threshold is too blunt for organizations with varied audiences across workspaces. Per-workspace configuration prevents over-blocking in permissive contexts and under-blocking in high-spam ones.
