That's the bigfoot b.s. again. Titor is coming back one way - it has been announced. He will be identified with a photo of his left hand. He has 12 days to show.
It's funny, because I know someone who thinks he is Titor and doesn't know it. I know someone who thinks he is the future Titor. Someone else thinks she is marrying Titor. I'm wondering what they are all going to do when their fantasies don't play out.
No one can say for sure.
Who is Titor? Ultimately, Titor is a large set of characters arranged in a specific order on a screen, and whatever truths can be derived and confirmed from the information contained therein. This is what everyone identifies as "John Titor".
This is the fundamental premise of the whole Titor saga. Thus whatever 'proof' there is must have qualifiers based on the posts themselves.
Again, ...For it to be confirmed as 'Titor', there must be not only a solid connection between the claimant's specific identity and the confirmed original posts, but also a way to confirm that the claimant was the one actually making the posts. If a claimant cannot meet that basic criteria of qualifiers, they are not 'Titor'.
That being said, consider all the other complications in trying to confirm the identity of Titor;
Because, presumably, humans have not 'yet' figured out time travel, if Titor is alive as per the original cover story, then he's a kid that doesn't know it unless he told himself via some cryptic means or someone else did. Which means he otherwise has to come in a time machine as an adult and expose himself to all kinds of risks and issues. Why would 'Titor' want to show up anyway? Why would he want to take such a risk?
Will he demonstrate his time machine to the world?
And not only would you have to meet the above mentioned criteria, but there would have to be TWO of them to confirm it through DNA match of differing ages, as well as family, etc etc.
And that is assuming it is physical time travel. How does multi-verse theory fit with all of it? What if time travel is not physical but technology assisted astral travel or remote viewing, or works like a radio where there must be a receiver, or is a way to tap into the internet of the past, or whatever. How does that work in all of it? If you don't understand the context of how time travel actually works, then you cannot say for sure what is really transpiring in the posts.
How do you know the cover story is even remotely accurate? It could all mean something else entirely.
How do you know it isn't more than one person all pretending to be Titor? ...or two of them taking turns, each playing the role of several people and scripting questions to themselves and/or each other?
It stands to reason that time travel would be a protected thing, thus there would need to be secrets and ways of communicating in order to protect those secrets. How many ways are there to encrypt something, and how can it be used when conveying information across time lines and multiple universes? How does that fit into all of it?
Why would a time traveler post on the net claiming to be a time traveler? Was it to send a message perhaps? An experiment maybe?
There are all kinds of questions that would need to be addressed in order to confirm who is 'John Titor'. It isn't going to be as simple as a hand and a photo, or whatever. Everything will have to all fall into place to define a clear and concise truth.
The fantasy is in wanting to believe in 'Titor' so much that one disregards reason in favor of a modern day internet Santa Claus.
