A person who first called himself timetravel_0, then John Titor started posting on an Internet forum from November 2000 to 21st~24th March 2001. He told of a tale of him, a soldier based in Tampa, Florida from the year 2036 and went back to 1975 for an old portable computer, IBM 5100 from his grandfather to fix a clock error in UNIX systems that occurs in 2038. He also spoke of a civil war in the United States from 2004/2005 to 2015 when Russian Federation launched nuclear attacks on USA and starting a short nuclear World War III which kills 2 billion people of the world. He also gave details of his time machine (called C-204, fitted on a vehicle), various details on time travel, the US Government, Mad Cow Disease, US Civil Rights and the worldline of 2036 (the one John Titor came from).
He said that all time travel paradoxes are false and the everett-wheeler model of world is correct (i.e. infinite worlds of ourselves of every outcome). Therefore, doing anything in the past would not have any impact on a specfic worldline as such actions (i.e. killing your grandfather in the past will only create another worldline without your grandfather and yourself).
Eeriely, most of his prediction have came true, especially the one involving high level physics, black holes, quantum physics and about the US President's many "lies".
Is this person an elaborate fraud, or he is really a soldier selected to return to 1975 to procure a IBM 5100 from his grandfather and will the US [second] civil war start and the nuclear WWIII happen? Discuss.
