there is no evidence SCP-3298 exhibits cognitohazardous 
properties. 


A period of SCP-3298 appearances to a target will conclude when 
the target reports receiving a message from SCP-3298. This occurs 
in the form of a visual hallucination where text being viewed by the 
target will change to a relevant message, which will be recognised 
as being related to SCP-3298 by the target even if the content is 
vague. This remains fixed to the target over time but is unable to be 
seen by other observers. Materials analysis of affected documents 
confirms the effect is hallucinatory only. While the content of these 
messages varies widely, targets consistently describe them as 
positive and affirmatory, and often results in the resolution of 
negative emotions related to SCP-3298.

Addendum 3298-2: On 01/02/20 , Foundation Agent Jeunet 
reported suspicions of being affected by SCP-3298 after a sighting 
of an individual in Toledo, Spain, which was deemed as a likely case 
of SCP-3298 after assessment by Antimemetics Division staff. This 
situation was considered an opportunity to apprehend SCP-3298 
and an operation was planned in which Agent Jeunet would be 
constantly tailed by 2 colleagues while being remotely monitored. 
SCP-3298 subsequently manifested in the presence of Agent Jeunet 
outside the Madrid Atocha railway station. A transcript of the 
encounter is attached below. 


Incident 3298-1: 


23/02/20 , 1539 hours 


Agent Jeunet sights SCP-3298 outside the Atocha 
station on the opposite side of the Paseo de la Infanta 
Isabel. SCP-3298 is later described by Agent Jeunet and 
civilian witnesses (under the effect of mnestic drugs) as 
an early-30s Spanish woman approximately 170cm in 
height, with shoulder-length brown hair and wearing a 
navy blue jacket and khaki pants (See image). 


Agent Jeunet waves to SCP-3298, who returns the 
gesture, and waits for traffic lights to change in order to 
cross the street to SCP-3298. The lights do not change 
for 8 minutes; after this time, Agents Amenabar and 
Ephron arrive on the scene in the guise of Madrid 
Municipal Police officers and halt traffic to allow Agent 
Jeunet to cross. When this occurs, SCP-3298 assumes a 
worried expression and begins walking towards the 
station entrance. 


All agents pursue SCP-3298 into the station. Civilian 
crowds outside are larger than usual for the time of day 
and Agent Jeunet has difficulty passing through them; 
these civilians pay little attention to the Foundation 
agents and react more slowly than expected to orders to 
clear the way. 


SCP-3298 is seen inside the station having crossed the 
ticket barrier. Upon passing through, the barrier returns 
an error message when Agent Jeunet's transport card is 
swiped. Agent Jeunet leaps the barrier but a Municipal 
Police officer attempts to intervene. This officer does not 
respond to Agent Jeunet showing police identification 
and the agents are forced to subdue him. 


At this point, SCP-3298 has boarded the 1606 Line C-7 
train. Before any agents are able to board, the doors 
close and the train departs ahead of schedule at 1603 
despite efforts from both the agents on site and in the 
operations center to contact the driver and prevent it 
from leaving. 


The train is stopped at the next station (Recoletos) and 
secured by Foundation operatives with the pretext of an 
anti-terrorist operation. Although there is no evidence of 
any passenger having left the train prior to this search, 
SCP-3298 is not found. A review of surveillance footage 
observes SCP-3298 passing between carriages out of 
view of cameras, but not appearing in the next carriage. 
In this segment of video, SCP-3298 is crying. 


Given the significant expenditure of resources in this operation for 
little result, no further attempts to apprehend SCP-3298 are planned. 
On 28/02/20 , Agent Jeunet reported seeing a message from 
SCP-3298 during a routine review of an unrelated Foundation file, 
which has been reproduced below. Agent Jeunet subsequently 
requested and was granted 1 week of personal leave. 


Sometimes | see someone on the street and | feel like we 
have a special connection. You have no idea how much | 
want to meet them properly, but it's better for everyone that | 
don't. 


| have one request, if it's not too much trouble. | know | have 
no right to ask this, but it would mean a lot to me, if you 
could. 


Don't forget about me. 


Footnotes 

1. Presumed singular; no simultaneous appearances of SCP-3298 
have been recorded, but the possibility of multiple SCP-3298 entities 
has not been excluded. 


SCP-3299: ONE WEIRD TRICK! (YOU WON'T 
BELIEVE NUMBER 8!!!!) 


Item #: SCP-3299 
Object Class: Euclid 


Special Containment Procedures: Major internet advertising 
agencies are to have their output automatically monitored by |/O- 
BEHOLDER’ for instances of SCP-3299; any such detected 
instances are to be deleted using previously installed Foundation 
trojan software, and attempts to track their source should be made. 


Any individuals discovered to have been affected by SCP-3299 are 
to be detained and treated on a case-by-case basis. The preferred 
treatment is the administration of amnestics and then release, but 
more invasive options are available as necessary, including but not 
limited to corrective surgery or permanent containment in the 
Anomalous Humanoid Wing of Site-17. 


Description: SCP-3299 is a series of cognitohazardous internet 
advertisements of a style that is colloquially referred to as "clickbait". 
Individuals who follow the link in the advertisement and read the 
headline and full body of the associated article are subject to its 
effect. 


When its effect is triggered, the affected individual is subject to one 
or more mental or physical alterations associated in some way with 
the headline and contents of the SCP-3299 instance they were 
exposed to. 


These alterations appear to be irreversible; amnestics have had no 
success in removing mental effects, though in minor cases physical 
alterations can be masked with surgery. 


To date there have been 247 different recorded varieties of 
SCP-3299. Their content varies significantly but in most cases tends 


towards the absurd. Refer to Table-3299-1 below for a list of 
examples. The origin of SCP-3299 is unknown, but attempts to trace 
its source have resulted in a pattern of inconclusive data matching 


that of SCP-2964.

Addendum 1 

On 11/03/2017 a new strain of SCP-3299 began appearing on 
websites served by popular advertising services. These new 
instances typically consist of only a headline and an image or video; 
in instances that contain text, the text is frequently nonsensical 
strings of random words. Additionally, reading the linked article itself 
is no longer required to trigger their effects; reading the headline and 
viewing the associated images/video is sufficient. Table-3299-2 
contains examples of this new strain. 


I/(O-BEHOLDER has been updated to check for potential future 
strains of SCP-3299 in addition to its usual monitoring activities.

Test Material: Head-First C# 3rd Edition (first printing), by Andrew 
Stellman and Jennifer Greene 


Results: A number of examples involving named male characters 
have had these characters renamed to Fred. The puzzles are also 
all filled in. Around page 100 or so, notes start appearing here and 
there. No substantial changes are noted until page 698, where a 
typo identified in the errata for the book was corrected. In 
subsequent pages, a number of typos and language problems were 
corrected in code snippets and descriptions, matching the errors 
reported in the errata, with the exception of screenshots. On 
returning to the journal, SCP-423 reported that it found that "fun, but 
unusual." On being questioned on its understanding of the 
language, SCP-423 stated that it could write and understand C#, 
and expressed a desire to use Visual Studio. 


Notes:"423 seems to be both capable and interested in learning, 
provided there is some narrative reason for it to learn. A potential 
future experiment could involve us attempting to decant it into a 
computer without an internet connection. - Dr. R. Karma"
