How Blocking Works in Bad Mobs

Bad Mobs does not delete entities that already exist - it filters new arrivals:

• Whenever an entity tries to join the world, the mod checks that entity's config section.
• If the route it used is disabled (allowNormalSpawning, allowSpawners, allowSpawnEggs or allowConversions), the entity is removed on the spot - it never appears, makes no sound and drops nothing.
• Mobs that were already in the world before you blocked them stay until they despawn or are killed; only new spawn attempts are filtered.
• Blocking is per entity id: blacklisting zombies does not affect skeletons, and passive animals keep spawning normally unless you block them too.
