I see little point in you posting this: There are no strict rules governing voting, merely guidelines; and they're not always followed. You could have gotten a downvote because some bird pooped on the reader's car, or because someone didn't want your answer to prevent such a badly formed question from being deleted by the Community bot. Unless someone is directly targeting your posts regardless of the content, no kind of voting for no reason would be abuse. —
