There have been so many threads about folks being a Time Traveler right from early days of "Ren, who claimed to be John Titor", that it's simply hard to know who's saying what.
Just like he has no way of *proving himself* 100% that he's a time traveler - we also have *no way of disproving* him 100% at least over internet that he's a hoaxer. Einstein asked him to get Headlines of a Newspaper for next 3 days, which he *can* do according to his own message (he can travel forward in this timeline which is ours) - but then he will not be able to travel backwards in this timeline, so may be that interferes with his mission (if he needs to be in this specific timeline), so he won't give you any headlines.
But then there's another thing you might say - what is so *specific* about this timeline, since he can not *pick* a timeline to travel back to, anyways. These questions I don't think, anyone has brought up yet, so I'll let him and others chime in.
Personally, I don't believe in asking theory questions - they might entertain you, but won't get you anywhere. Ponder this, Lussorio and others:
- Do you know John Titor or heard of him? Does he exist in your timeline?
- How about posting photos of your time machine unit like Titor posted?
- How about a video of yourself disappearing from this timeline when you finally leave
- Do you have confidantes in this timeline who know about you?
Peace to you whoever you are
