What can cause my question to be bumped?
At first I was shocked to see that these questions showed "2 mins ago" with 6K views, and the question too is not challenging. I wondered: how come a simple question gets 6K views with 5 answers and 7 votes in just 2 mins? But then I opened the question and found that the question was asked 2 years ago and it was already answered years back.
So: why were these answered questions placed on the questions page again today? This is not the first time, I found many questions of such kind in Stack Exchange sites. If unanswered questions or challenging questions are re-posted there will be a use. Can anybody tell me why and how these questions get reactivated?
