This user is only displaying 56 rep. https://stackoverflow.com/users/2354107/user2638924
But surely (s)he has much more than that.
The user has also never given out any bounties.
Also, badges are missing:

16Well, take a look at this!– Shadow Wizard Is Vaccinated V3Dec 20 '13 at 21:58

2@Shadow There's literally nothing in his history that would indicate something happened here. Definitely only the devs would be able to answer this one.– animuson StaffModDec 20 '13 at 21:59

3@animuson true. I shudder to the thought this will happen to Jon Skeet... imagine he suddenly have a drop of 500,000 points!– Shadow Wizard Is Vaccinated V3Dec 20 '13 at 22:01

3@Shadow Wizard, a thousand of us would probably award a 500 rep bounty to one of his answers.– Frédéric HamidiDec 20 '13 at 22:04

2It seems this just happened within the last day. If you look at his profile activity you see that about 8 hours ago, he is "JoeZ". About 7 hours ago other people call him "user263...".– chue xDec 20 '13 at 23:21

1This happened to me too.– joshreesjonesDec 20 '13 at 23:32

1Whatever happened has been reversed. The user's rep is now 8,928.– Josh CrozierDec 21 '13 at 3:56

8I appreciate everyone looking into this. My rep eventually came back, although I did have to reset my name manually. It was the strangest thing when it happened. When I went back to my profile page, there was a green bubble over the Reputation tab that said something like -8752 or the like (I didn't remember the number, I just remembered it was large and negative), and my rep had dropped to 41. I had come to my profile page when I noticed my name started showing up as user2638924 instead of "Joe Z." My rep eked back up to 56 when someone accepted one of my answers.– Joe ZDec 23 '13 at 6:58

20We are aware of the issue and are looking into this, though I don't expect that anything will happen before the new year (people are on vacation at Stack Exchange too...).– OdedDec 23 '13 at 21:22

3@Oded here is another one for you.– Shadow Wizard Is Vaccinated V3Dec 26 '13 at 14:08

1@gnat - it might be related - a cached value certainly looks to be the culprit. I am actually taking some time off - so not really had a chance to investigate this (and most of the devs are taking a few days off as well, so this may have to wait till after the new year)– OdedDec 26 '13 at 20:25

4Is this user one where the issue has come and gone, and they are just not around (last seen Oct 24 '11) to change their display name back? Or did they really post ~2,500 answers under the autogenerated username?– Josh DarnellDec 27 '13 at 3:17

A fix or this was just deployed, sorry it took so long to track down. The root cause was review audits, the common pattern in these users was they were owners of a post used for a positive review audit in the first post review queue.
Down in the code was this:
post.Owner.Reputation = deterministicFakeStats.Next(0, 10) * 5 + 1;
post.Owner.BadgeSummary = "1=0 2=0 3=0";
The issue was that post.Owner is a Lazy load of a User via User.Get(int id), which is a Linq2SQL query. This means the loaded user is in the relational mapper so when sometimes a SubmitChanges() is later called for another reason (rotating a user cookie, etc.) they get saved. What do they get saved with? You guessed it! a random-ish low amount of rep and no badges.
The change is simple:
- var post = Post.GetReadOnly(reviewTask.PostId);
+ // Note we're loading the owner here as to not screw with the actual database
+ // Otherwise, a Post.Owner trigger of User.Get() underneath would cause mutation on audits
+ var post = Post.GetReadOnly(reviewTask.PostId, Post.UserLoadMode.Owner);
We have a few overloads for the Dapper-based Post.GetReadOnly(), the UserLoadMode.Owner of which will load the User object via a LEFT JOIN where the Linq2SQL mapper is unaware of it, preventing any mutation if a save is called later in the request.
There may be a few more comments added further down too...

Awesome! But it means it happened for long time, wonder how we missed it before. Also, curious to know what restored the rep and badges back to normal? The latest victim for example was affected for long hours, even after being upvoted and downvoted. Jan 22 '14 at 8:13

1@ShadowWizard there is a job that runs nightly that sums up everyone's rep history and compares to their current rep - if it doesn't match it recalcs them to make sure everything's right. The count affected is metric I'll be adding to our new monitoring system so we can see when a source of skew is introduced in the future. Jan 22 '14 at 10:01
-
@Nick thanks. Hmm... but it means badges are also re-calculated? Can't it lead to losing some badges that aren't eligible anymore after the recalculation? Jan 22 '14 at 10:19
-
1@ShadowWizard a rep recalc doesn't affect badges, and the badge counts sync with current actual badge counts via another nightly task as well. User to badge mapping rows in the database aren't added or removed by either process. Jan 22 '14 at 10:30
Until this is fixed, I'll keep here a "log" of the victims, starting now. If anyone spot any other victims I miss don't hesitate to edit it in here as well, I've made it CW on purpose.
What they have in common? So far all I could see is that all victims have accounts on other Stack Exchange sites, most including account here on Meta and more than 1000 rep before the reset took place. (not all though)

1As I posted on the question, I wonder if this user was affected, and is not around to change his name back (hasn't been seen since Oct 2011). According to the comments on several of his posts (this question, and its answers, for instance), it seems his username was patrick_dw at some point. Jan 21 '14 at 15:21

2@jadarnel27 - Unlikely. He's had that username since at least last August 2012. wayback machine Jan 21 '14 at 15:25

Please remove the screenshot of my personal info from here. I don't see how it helps you troubleshoot. I am user2808697. Jan 21 '14 at 15:56

2@sedefcho it's not personal, everyone can see it by clicking your name same way you can see anyone's profile on any site. It help by keeping a log of the affected users. Jan 21 '14 at 15:58
-
@ShadowWizard I know that of course. But if I remove it later, it will still stay here. OK? And the rep loss is wrong btw. Jan 21 '14 at 15:59

I think my reputation was 7165 on SO before this happened. Now I am at 39 :) / sedefcho == peter.petrov here in meta /. Also, I see my nickname on SO is gone too (was peter.petrov, now just user2808697). Jan 21 '14 at 22:14

1@peter.petrov true. The bug affects reputation, badges and display name, resetting all to default. Reputation and badges restore themselves at some point (see other cases linked here) but you have to change the display name manually... you can do it now and it will stay. Jan 21 '14 at 22:18
