blockPublicAcls

Specifies whether Amazon S3 should block public access control lists (ACLs) for this bucket and objects in this bucket. Setting this element to TRUE causes the following behavior:

• PUT Bucket ACL and PUT Object ACL calls fail if the specified ACL is public.

• PUT Object calls fail if the request includes a public ACL.

• PUT Bucket calls fail if the request includes a public ACL.

Enabling this setting doesn't affect existing policies or ACLs.
