Out or curiosity.

I had 460 reputation points (as demonstrated on the attached image)


Went off answering question and searching for relative answers using other tabs on the browser.

password search

At some point, 30 minutes later, I noticed that 10 points were deducted from my reputation.

I received a message on my inbox and also glanced at my reputation. I saw it being down by 10 points. Checked the message which I found to be irrelevant to a rep deduction.

450 points

Had a look at my reputation page.

But no such action was recorded. No "downvotes", no "un-upvotes", no "removed posts". Nothing. I did not even have any notifications on the Achievements bar.
Being curious I made the screenshots and rechecked 3 hours later. "Let the system work", I thought. Nothing had or have changed so far.


Out of curiosity. How did this happen? Was it a fluke or a bug?

  • Did you check the box "show removed posts" at the bottom of the reputation tab of your activity page?

  • @sandwich Yes. As stated. No "downvotes", no "un-upvotes", no "removed posts". Nothing. May 16, 2016 at 4:53

A Moderator is probably necessary to know for sure.

I think the most likely scenario is that you just happened to catch your reputation after someone upvoted one of your answers but before they changed their mind and removed the vote within the grace period. That wouldn't record an "unupvote" event in your reputation history.

Why it took 30 minutes or so for you to notice isn't surprising considering how much caching is used on these sites.

  • This is more than likely the case.

  • Confirming - that's exactly what happened.
