When you're administering a server, that's the difference between Silence and Suspend. If a server's content causes problems but it'd be fine if users followed them, then they're "Silenced" (on some servers this shows up as "Limited Content"). If an instance doesn't want their content no matter what, it's "Suspended". For most instances, other instances are only suspended if their "inappropriate content" is often illegal.
