The debian-private mailing list leak, part 1. Volunteers have complained about Blackmail. Lynchings. Character assassination. Defamation. Cyberbullying. Volunteers who gave many years of their lives are picked out at random for cruel social experiments. The former DPL's girlfriend Molly de Blanc is given volunteers to experiment on for her crazy talks. These volunteers never consented to be used like lab rats. We don't either. debian-private can no longer be a safe space for the cabal. Let these monsters have nowhere to hide. Volunteers are not disposable. We stand with the victims.

Simply because people remember coincidences.  How many projects are
there which DON'T have four people named Martin?

This is the birthday paradox.  For n people, the probability that
there are two (or more) people with the same birthday is:

         365!
1 -   -------------
      (365-n)! 365^n

For 30 people, the probablity is 0.71.  You only need 23 people to get
a probablility over 0.5.
