The true nature of SCP-2950 is that of an extremely dangerous infohazardous entity that takes the form of whatever the majority of people think it is. If the majority understand its true nature and that danger it presents, it would become something so horrible and terrifying that it could easily destroy the world. For this reason The SCP Foundation erased the memories of everyone who knew about it except O5-6, who subsequently convinced people everyone that SCP-2950 was harmless. It's true classification is Keter.
