Description

I think I have a partial solution to Facebook. I don't know how you've implemented search for it. But, when I took a look on profile HTML, I found a simple difference between a login that doesn't exist, and a login that exists in fact.

In my tests (I made dozens), I could see that non-existent logins have

in HTML, while existent logins don't have it.

However, it's partial. Unfortunately, I think that, depending on profile configuration, it shows a result as if the profile does not exist.
