Are passwords for the same mail address deduplicated?

[domenukk]

Looking through recent leaks, I found mail:password combos that are contained particularly often.
This, however, does not indicate it would be more commonly used. It should still count as a single occurrence.
Is this taken into account?

Yes.

In revisions 1 and 2, a password's popularity is determined based on the number of source files it appeared in, not how many times it appeared in each file. Each source file was stripped of all non-password information (as much as possible), and then had duplicates removed.
