Sometimes I read a particular user's answers (why else does the profile page exist?). I remember awhile ago, I went through one user's posts and saw a lot of low quality answers. I was independently evaluating each answer, and I determined independently that they were bad answers so I downvoted them. My downvotes were removed later automatically, I'm assuming for "targeted voting" which I know is bad on this site. However I was kind of shocked. These were bad answers, and I was not just attacking a user. I was independently evaluating different answers to be poor, they just all happened to be from the same user.
Now I rarely read a user's answers who posts a lot of poor answers, because I don't like reading poor answers (the one user, posted a lot of bad answers in an amusing way). However the converse is quite common. I often read through a user's profile page if they post a lot of great answers. I want to upvote all of them, because they are all good.
Is this targeted voting? Even if I independently evaluate all the answers to be good or bad? If I think one particular user has 20 bad answers, worthy of a downvote, how do I downvote all 20 of them without the system reversing it? If I think one particular user has 20 good answers, worthy of a upvote, how do I upvote all 20 of them without the system reversing it?
