We use the permissions feature “Access Other Authors' Content” to restrict several accounts. This concerns interns and freelancers. But when the restricted access is activated, these people cannot add stories to the related items area, which we use to build link-boxes in our stories. Meaning: An intern can’t link to other authors' stories. Arc tells me that this is expected behavior but I disagree - an intern couldn't possibly do any harm by adding related items that they don't have edit access to.
