All voting is anonymous (both positive and negative). If you hover over the downvote button, it reads:
This question does not show any research effort; it is unclear or not useful
Hence was deemed to be that way by at least 3 users.
Your comment here:
What is it with the -3 ? Is anyone allowed to dis a question and remain anonymous? What kind of forum wienie behavior is this?
is not necessary, given the amount of time you have been a member, surely you know that the downvotes are not personal, and would know that they are related to the quality standards laid out in the help pages.
Also, Stack sites are not forums.
