That is correct. I'm pointing it out because the "non-communicability" aspect is a whole genre called "infohazards", which is any SCP triggered by or involving communication. It's a very popular tag.

You might contrast with SCP-2521 that attacks those that use written or spoken language to refer to it, so the documentation page is one giant infographic without text.[1]
