<p>Think I am experiencing a weird stalk-upvoting behaviour this week. Every day I see 2-3 of my old answers being upvoted. And the upvoting started from the lowest-score answers (that had 0 score) and seems to be moving upwards.</p>

<p>I am not sure if the system is reverting or will revert the score from those votes. And obviously I am not upset about it. But my question is - what am I supposed to be doing in this case? Should I report this somewhere?</p>

<p>Whoever is doing it seems to be familiar with the SO system and visit this site every day.</p>
