SCP-2521, also referred to as "█████", is a Keter-class anomaly characterized by its unique method of acquiring information about itself. The entity appears to manifest and abduct anything containing information about it conveyed through written, digital, or verbal communication. Due to this behavior, SCP-2521 cannot be directly described through text, speech, or recordings.

All descriptions of SCP-2521 must be provided exclusively through pictograms, diagrams, or non-verbal means. This limitation is essential to prevent its manifestation and subsequent abduction of information.

SCP-2521's behavior suggests sapience, as it appears to actively seek out such information. Instances of its manifestation involve its immediate and unpredictable appearance near the source of communicated data, followed by the removal of said data and any associated medium (including personnel, documents, and devices).

Containment of SCP-2521 is achieved by adhering to strict non-verbal documentation protocols. All personnel are instructed to avoid discussing or documenting SCP-2521 using conventional methods. Any breach of protocol is met with immediate termination of affected media and, if necessary, quarantine of involved individuals.
