I was involved into stupid situation. One person on this site has strange behavior. He has his own opinion (maybe, I hope :) ) and just downvotes without any reasons. I asked, what is going wrong. No answers. As I know he is a famous downvoter on many stackexchange family sites. How do professionals and enthusiasts prevent again so strange persons?
As I understand these persons smooth the general picture by doing so stupid matters. It is a bad luck. No comments.
