Out of curiosity, nothing urgent. I have spotted, over last couple of months, few poor quality questions from same user, having an alias quite easy to remember. I seem to remember having answered few of them, but now I can't find anything but the most recent question from today. What is more confusing, the profile of the user indicates he has been member for 1 year and 1 month, while he is being shown with New contributor tag. Could this be a new user signing up with the same alias, or? Could this be caused by the only visible question being from today, as I also suspect him of deleting his old questions.
New contributor
tag is based on reputation, not account age. If this user is in fact an existing user all of whose contributions have been deleted and who hasn't otherwise built > 10 rep, they would get theNew contributor
tag.
