Not easy indeed, often impossible, and in some cases this question does
not even make sense.  For example, if you contribute the password "A",
I run my ruleset on it and come up with the password "A1" as a result
(for another hash), who contributed "A1" - you or me or neither or both?
Then "A1" gets reused even further.  One of us looks at it, notices
"B1" as well, comes up with a "u $1" rule, and cracks "D1" through "Z1".
Who contributed that?  This is team effort, really. :-)
