2014年9月21日 · SCP-513 Why don't they just stick it in a box and leave it alone? Nothing in the article says it would get out somehow, and no one in the discussion thread has said anything about it. If you can't see it, touch it, or hear it, it's totally harmless. Unless I'm missing something, in which case please point it out. And I screwed up the title. Damn.
