I noticed a network profile of a user with the age shown as -972:

I dug further to see if there are more such cases but my analysis shows that this is a lone case, though there are a lot of users who have not added their age to their profile. I believe it is a bug in the system that allows the users to enter negative numbers as their age.

I emailed Stack Overflow team about the same and I was suggested to use Meta for discussing it further. I would like to know if this is indeed a bug or there is some explanation behind this.

    Hmm.... trying to reproduce in the easy way failed: i.sstatic.net/NyxIN.png Aug 8, 2016 at 5:45
  • Probably this filter was added later? Moreover this is the only case of its kind as I checked using the latest StackOverflow user data dump Aug 8, 2016 at 5:46

    Maybe... or maybe that user was really born in 2988 and returned back to the past.... :D Aug 8, 2016 at 5:51

As the reference from this answer from the Stack Exchange developer, displaying Age from the profile was removed from per-site and network profile.

So hence this problem has been solved.

The actual answer from Michael Stum is:

That was an oversight - we removed Age from Profiles ages ago, but still had the code in. When looking at removing the code completely, I saw that SE.com still uses it, and we removed it there as well now.

Also screenshot for the confirmation:

Age removed
