More than half of my posts has downvoting without any comments.

I believe that downvoting without explaining the reasons, as well as anonymous downvoting, should be prohibited.

What is the sense of seeing my questions or answers anonymously or unreasonably downvoted?

I think enormous amount of new-coming professionals are repelled from the site by it.

I believe that moderators should monitor repelling-activists and apply publicly viewable measures against them...

What do you mean that I have not looked into what I had written? It is a waste of time to argue with you about manners or even read your posts.

What is the point in upvoting incorrect answers and downvoting, for ex., in 

 - https://serverfault.com/questions/170195/how-to-back-up-a-mssql-database

or even deleting, for ex., like it was with with my answer in

 - https://serverfault.com/questions/170476/windows-server-2008-connecting-to-127-0-0-1/ 

the correct answers or useful discussions?

Should I extend the list?

**@Zoredache**,

you are also in my list of spammers and abusers. The guy who closed half a dozen of my questions and deleted the only (my) answer in 

 - https://serverfault.com/questions/170476/windows-server-2008-connecting-to-127-0-0-1/ 

which was recognized by answerer as answer...
