SCP-XXXX-J (Memetic Keyboard Button)

Item number: SCP-XXXX-J

Object class: KETER

Containment procedures: SCP-XXXX-J cannot be contained under any circumstances.  It is present on every single computer keyboard in the world, and the keyboards of nearly every other electronic device.  Therefore, a public ad campaign is being maintained by the Foundation (codename “stfu, n00b.”) in order to reduce public usage of SCP-XXXX-J.  If an instance of SCP-XXXX-J-1 is encountered in the wild, Foundation personnel are required to immediately administer banning to the perpetrator.

Object description: SCP-XXXX-J is an anomalous button that appears on every modern computer keyboard, located above the left Shift key and below the Tab key.  The button functions as a toggle, with each press switching its effects on and off.
While SCP-XXXX-J is activated, any text typed by the user will be altered.  Such text is an instance of SCP-XXXX-J-1.  The text will appear larger, and the shapes of the letters will be changed, however, their meaning will still be clear to readers through an unknown process.  The text exhibits strong memetic properties in readers.
Any human who reads an instance of SCP-XXXX-J-1 will become subjective to it memetic effects.  SCP-XXXX-J-1 will be perceived as irritating, obnoxious, and generally repulsive, regardless of the actual message.  In 90% of cases, viewers of SCP-XXXX-J-1 will respond negatively to the text, often attempting to silence the individual who posted the original instance.  In 30% of these cases, the individuals will respond with an additional instance of SCP-XXXX-J-1.  This can cause colossal chain reactions of negativity, hereafter referred to as a Flame War event.
SCP-XXXX-J is itself memetic as well.  Computer users may feel the need to use SCP-XXXX-J for one reason or another, with children under the age of 14 being most susceptible.
