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.
