From what I remember, Sec.SE sorts answers based on the net vote score. If an answer is accepted, it is moved to the top automatically. In fact a question I asked became a hot network question. I accepted the answer that had the second most number of votes, which bumped it up to the top, resulting in people upvoting it until it had the most votes. This was just a few days ago, so at that time I was sure that accepted answers were automatically put on the top. However I came across a question where the top answer score is 1 (+2/-1), with the answer below it having no votes, but being accepted. I am sorting based on vote count. Does this mean the sorting algorithm has been changed and the accepted status of an answer no longer pushes it to the top?
EDIT: I now also see another question where the expected behavior occurs (the accepted answer, despite not having the most votes, is at the top). This is confusing me.
