The revision page has no sign of the user sharth
The user's activity also does not have any sign of related activity
I would like to know why the user's name is associated with the question. At least why their display name shows up as having modified the question timeline activity.
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.
