<p>I have noticed an unexpected upsurge in the frequency by which my past questions are being upvoted. Whereas for most years of my membership I had maybe on average one or two upvotes in a week, since about two weeks now, I have had multiple upvotes per day. My score has risen +294 in the past week (rank #40) and I am among the top 5% this week.</p>

<p>This may be a coincidence or related to more frequent usage of CV in general, but it still seems very odd to me. Has anybody made similar experiences?</p>

<p>A similar question has been discussed in this <a href="https://stats.meta.stackexchange.com/questions/5462/i-get-surges-of-upvotes-and-they-are-lumpy-in-time-is-this-because-the-site-is">thread</a> and this <a href="https://stats.meta.stackexchange.com/questions/5111/odd-upvoting-pattern">thread</a>. Several answers are given:</p>

<ol>
<li>Somebody found an Q/A they liked, clicked on profile and found more Q/A they liked; including giving you a boost because your Q/A's were under-appreciated.</li>
<li>It happens all the time. (not sure what this means?)</li>
<li>You have a fan.</li>
</ol>

<p>I find these explanations still somewhat unsatisfactory. In particular, I have had around three upvotes per day. If explanation 1 or 3 would apply it is likely the upvotes would stop after some days. I really judge it unlikely anybody will come back to my profile over a period of weeks to vote on 2-4 questions per day. Explanation 2 seems to hint that this is a common problem of unknown origin. I somehow feel that there is more than this going on, but perhaps not.</p>
