First, full drafts aren't permitted in the forums. That's what the sandbox is for.
Second… is this supposed to be a Joke SCP, or a Mainlister?
joke, and btw i fixed it so its a link to the sandbox
Joke SCPs are jokes in SCP form. As such, you want to avoid giving away the joke before the punchline, or explain it.
SCP-2672 is a small metal box that within radius, doesn’t allow you to finish your sentence. It can cause you to go crazy and you can’t tell anyone because you can’t finish your thought.
And you kinda do both here. It kills your joke before it can get off the ground.
I'd suggest you try to have the description itself reflect the nature of the SCP, where it keeps getting cut off despite a half-dozen attempts at finishing it.
You also need to have -J after the SCP number.
