I saw an answer recently which was very different from all the other answers. It had downvotes, but the author had said someone was deliberately targeting him and downvoting his answers. I looked into his profile and saw multiple such answers which were very debated upon and also some questions where the comments were full of conflicts.
Seeing all this, I am quite tempted to ask for the user's credentials as he doesn't mention anything in his profile and has answered one of my questions.
Is this allowed?
