Playing around with the Data Explorer, I noticed two users with remarkably similar handles, Zhak Maarli and zhak maar li. Curious, I went to the Users tab, searched for "zhak", and... got zero results.
The users do exist, though; they haven't been deleted in the mean time, and I even logged out to verify that I don't see them due to my 10k powers or something (which would be news to me, but who knows):
- https://english.stackexchange.com/users/1152/zhak-maarli (88 rep)
- https://english.stackexchange.com/users/1507/zhak-maar-li (21 rep)
Going by the rep, the first user should appear on Page 75 in the Users tab, but he doesn't:
I did notice that both users haven't logged in for more than three months, but that can't be the reason (case in point: Ex-user, who's still listed on Page 1).
That leaves me wondering how many other users might be missing from the Users tab and why.
Searching the meta Meta, I have only found this, which raises more questions than it answers.
