The revision page has no sign of the user sharth
The user's activity also does not have any sign of related activity
It's a minor thing, but I would like to know why the user's name is associated with the question.
Possible reason that I can think of is that, the user answered and then deleted the answer.
Is this the reason?
Is there a way (for normal users), to look for such details, other than looking at the user activity and the question's revision history.
