A Foundation program embedded in Google's popular Gmail email client intended to stop the accidental creation and dispersion of SCP-XXXX instances.

Item #: SCP-XXXX

Object Class: Keter

Special Containment Procedures: Due to their ability to be accidentally created by anyone capable of writing, Foundation efforts are instead focused on limiting the spread of SCP-XXXX instances after they are created. Mobile Task Force Eta-11 ("Autocompleters") is to lead these efforts, focusing on the rapid identification and destruction of SCP-XXXX instances, along with the creation of programs embedded in various social media websites to stop their inadvertent creation and spread.

Description: SCP-XXXX is a cognitohazard created when any piece of writing claims to provide additional information but does not. If a human being views an SCP-XXXX instance, they become an instance of SCP-XXXX-1. SCP-XXXX-1 instances are noticeably more pessimistic than before, refusing to believe in anything they can't see and is not strictly rational. The mechanism by which this change takes place is unknown. Writing about SCP-XXXX does not appear to fall under its effects.

Addendum XXXX-A: Known instances of SCP-XXXX:

Signs instructing observers to call for more details without including a telephone number to call.

Emails including a variation on the phrase "I've attached some files below" without attaching the files.

An academic paper written by Professor M██████ P██████████████ of P██████ University, with the following footnote: "Additional information on beta-sheet contact prediction can be found in ."

The documentation for SCP-2140, which mentions appendices with additional information, despite the fact that said appendices do not exist anywhere on the Foundation database. (ask about cross-link)

Foundation Researchers have hypothesized that exposure to SCP-XXXX may have influenced philosopher Immanuel Kant's belief that morality is derived from the innate human ability to reason.

Addendum XXXX-B: Event XXXX-1992-001:

The effects of SCP-XXXX were discovered on 2/25/1992, as a result of the actions of a millenarian cult known as "The Disciples of His Arrival." The cult planned to commit mass suicide in S█████, Arizona, on that date in order to reach a spacecraft approaching the solar system (later designated SCP-████ (this is intended to be 1281 but it really doesn't matter)); the methods by which they detected this SCP are unknown). A speech was written beforehand to be delivered on the occasion by A█████ Z█████, a leader of the cult, and intended to be taped as the last thing the cult left behind. Immediately following the speech, all 25 members of the cult were to commit suicide by drinking Kool-Aid laced with cyanide.

Transcript of Event XXXX-1992-001:

Z█████: "…so it is now that I say farewell! Farewell to the sinners! To those who do not believe! I tell you: we wish that you will see the light and join us. You will find– [the writing trails off here, apparently unfinished]"

At this point, Z█████ became very distraught. After a 10-second pause, he began again.

Z█████: "Please leave. This is my property. You have no right to be here. Don't drink the Kool-Aid. The Harbinger isn't real. We can't prove it."

The other 24 members all begin to drink the Kool-Aid. As they all die, Z█████ approaches the camera.

Z█████: What was I thinking?

Z█████ shuts off the camera.

It is as of yet unknown who wrote the speech, or why it was unfinished.

The event was brought to the Foundation's attention when it was reported by the S█████ Seer as "LOCAL CULT LEADER SUDDENLY RENOUNCES BELIEFS BEFORE CULT COMMITS SUICIDE." Mobile Task Force Eta-10 ("See No Evil") raided the cult's meeting house, discovering the recording and written speech. The story in the Seer was an effective cover story, so it was not changed. Z█████ was brought into Foundation custody to research the anomaly. As Foundation researchers discovered more about the anomaly and understood its scale, Mobile Task Force Eta-11 ("Autocompleters") was created to effectively combat it. To date, over ████ instances of SCP-XXXX have been identified and neutralized.
