I think in a SE site, someone has picked on me by voting to close all my questions. This has been the case for more than one month. As a result many (not all) of my questions are closed. Flagging a post does not show serial voting and moderators may say anyone has the right to vote. But it seems unfair when someone picks on a user. When first close vote is given in many occasions other reviewers trust the first voter and close the question. This is because, when someone considers a question to find a reason to close it, they will find a justifiable reason in most occasions.
When the specific user sends the first close vote, almost half of the questions are closed. Then when I vote to reopen them, half of the closed questions are reopened. I think the vote of first voter is decisive. btw, it seems frustrating if some user picks on another one to close his questions, which is clearly personal. It is fair if there are different first voters for some user's questions. But if the first voter is the same for all of them over long time, is it normal?
I do want to consider my case. But what Can someone do in a similar situation? When the user sees the the first close voter to all of his questions is the same?
I think there must be a software limitation for serial close voting (as the first close voter to a particular user's questions), so that a particular user can send one or two close vote as the first voter to a specific user over a period of time. Or the first close vote be hidden until a second one is received normally. Or at least there should be a private message system so that one can talk with a moderator about it privately (flaging does not provide a discussion environment). It does not seem fair that someone can send a serial close votes to the same person, In my case every week a specific user opens my questions and sends a close to all of them.
I do not request to consider my case, so it does not help if I say which user did this in my case, I'm requesting to add some software feature which prevents this automatically, as is the case for serial downvotes (which are reversed automatically).
