Item #: SCP-3631
Object Class: Euclid
Special Containment Procedures: All activity on SCP-3631’s current host site is to be saved, filtered through standard RAISA anti-infohazard procedures and monitored for any evidence of SCP-3631 infection.
Late-stage SCP-3631-1 infectees are to be terminated without exception. Subjects in earlier phases may be terminated or remanded to local sanatoriums, subject to the discretion of the overseeing researcher.
All occurrences of SCP-3631-3 are to be terminated with extreme prejudice and all traces of their existence removed.
The properties of SCP-3631-2 individuals are extremely helpful in the containment of 3631-1 instances. In order to best exploit these properties, socioeconomic manipulation of -2 individuals may be employed to encourage their tendency to group together. At present three (3) major clusters of -2 instances exist in ████, US ████████, FR, and ██████, SA.
All Foundation personnel are forbidden to have or operate a Tumblr account at any time. All personnel are also forbidden from visiting the website for any reason other than testing purposes or information suppression.
Description: SCP-3631 is the collective designation for a pair of phenomena which afflict approximately zero-point-zero-three percent (0.03%) of visitors to the social media site Tumblr.
Any attempts to contain SCP-3631 at the source invariably fail. Once the website hosting SCP-3631 begins to suffer a net loss of unique users over a three month span, the phenomenon will shift to a new host site.
Curiously, SCP-3631 has yet to transition to any of the dominant social media sites such as Facebook or Instagram, and instead targets smaller concerns which have specific niches or functions. The significance of this is unknown at this time. Proposals to deliberately cause the stagnation of an SCP-3631 host site once it reaches a certain userbase size are under consideration.
The parameters which determine infectees are unknown. However it has been determined that of SCP-3631 infectees, those who score higher than thirty-five (35) on the Empathy Quotient test (out of a possible eighty (80)) will be affected by the first strain, designated SCP-3631-1, while those who score lower than this will be affected by the second, SCP-3631-2.
SCP-3631-1 begins by compelling in the infected subject an interest in “furry”, “otherkin” and associated internet subcultures which in some way relate to empathizing with, or pretending to be, animals.
Progression rates vary hugely and are dependent on an array of psychological factors, however infection generally follows the same stages:
•After an initial period of researching these online subcultures, the subject will become convinced that they are at least partially non-human. The creature identified with varies greatly, but can include fictional creatures and even, in one alarming instance [DATA EXPUNGED].
•After this “self-discovery”, the subject will integrate into one of the previously observed subcultures. At this point the subject’s affliction is heightened by the echo chamber effect, with each member reinforcing each other’s behaviour and beliefs.
•Eventually this leads to subjects altering their outward appearance and behaviour to better suit their psychosis. As can be expected, this results in an exponential increase in social isolation for 3631-1 subjects as they begin performing actions such as growling and snarling at other humans they encounter, securing fur to their skin with pins or adhesive, splitting their upper lip with bladed objects to form clefts, and ceasing to bathe. At this point fatalities begin to occur as subjects lose their jobs and become unable to feed themselves, mutilate their own bodies without seeking follow-up medical attention, become unable to leave their homes (no longer believing themselves to be capable of opening doors), or freeze in the headlights of oncoming cars.
•After some time the only behaviour undertaken by 3631-1 subjects that can be attributed to humans is continuing to participate in their online community. Once external factors render this untenable, the subjects will leave their homes and migrate to an apparently random patch of woodland located at least 15km from any densely populated areas. Once there, they will begin imitating the behaviour of their identified-with animal. At this point subjects are designated SCP-3631-3.
All subjects who progress to -3 stage infection within a wide geographic area will migrate to the same patch of woodland, despite many subjects never having communicated about this location with other subjects.
Research indicates that the ability of -3 instances to survive in the wild directly correlates to whether their identified-with animal would generally thrive in the chosen habitat. It is speculated that many -3 colonies could maintain breeding populations were it not for intervention by the Foundation and SCP-3631-2.
SCP-3631-2 begins similarly to the -1 variant, with an increased interest in internet subcultures based around identifying with animals. However whilst 3631-1 subjects approach these subcultures with interest and curiosity, the reactions of 3631-2 subjects are characterised by contempt and disgust.
3631-2 progression proceeds as follows:
•-2 subjects expend all possible effort, skills and resources to disrupt the online activities of -1 infected individuals. The methods used include but are not limited to hacking, flooding 3631-1 pages with violent images or other content intended to cause distress, threats of murder or sexual violence, and the uncovering of -1 subjects’ personal details so as to attack their families or employers.
•-2 subjects coalesce into communities with other -2 infectees, and quickly form bonds of camaraderie with each other. Most -2 communities focus their efforts upon singular -1 communities in a parasitic bond, with the -2 subjects growing in number and aggression as the -1 community grows in size and advances in infection.
•At this point the advancement of the -2 phenomenon is dependent upon the development of the corresponding -1 community. In many cases, the efforts of -2 subjects are disruptive enough to splinter the corresponding -1 community and effectively reset the progression of all individuals involved. However, if their efforts are unsuccessful, 3631-2 instances’ disgust for -1 instances will exponentially increase as they observe -1 individuals going through the social isolation phase, eventually culminating in the decision to hunt down and terminate a -1 instance.
•In areas which possess well trained and equipped law enforcement, -3631-2 hunting patterns will resemble those of successful serial killers, prioritising the preservation of anonymity and a determination to not be apprehended, even when this constricts personal enjoyment. In areas where rule of law is lax, -2 subjects will often adopt the mannerisms and apparel of hunters from their origin culture, and treat the hunt as a hobby to be enjoyed or even prolonged.
Addendum 3631-1: RAION-ORION events:
In the event of a 3631-3 colony attaining more than twenty (20) members, the nearest instance of 3631-2 will immediately become aware of it by anomalous means and be compelled to tell their online community. This news quickly spreads to other -2 communities, who will mobilize to meet at a real-world location near the -3 colony within 48 hours.
All 3631-2 individuals who are aware of the event and are physically able will congregate at the designated location. Several hours of jovial ‘meet and greet’ will then ensue, with -2 instances who have previously hunted and killed a -1 instances being granted great respect. Once this period concludes, these revered individuals will lead the group in planning and then executing an assault upon the -3 colony.
The attack invariably results in the termination (or capture and subsequent torture and termination) of all -3 instances. Extremely infrequently, -3 instances who identify as predatory animals will fight back and kill a -2 instance, who is later buried in a solemn and venerable ceremony by their fellows.
Once all -3 instances are dead, -2 instances will proceed [DATA EXPUNGED].

Addendum 3631-2:
Following deliberations by the O5 council and minor debate within the Ethics Committee, it is decided that 3631-2 instances and RAION-ORION events are invaluable resources in the containment of 3631-1 and -3 instances.
MTF Omicron-14 (Houndmasters) have been given dispensation to assist -2 in organizing and equipping for -1 community disruption and hunting. Omicron-14 are also ordered to join -2 instances during RAION-ORION events to ensure total sterilization of -3 colonies and amnesticization of civilian witnesses.
Class-A amnestics are to be made available to Omicron-14 personnel following these events.
