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.

Scary isn't it? I don't know what it causing the problem, but it's
sure not security in my in.telnetd, maybe you suffer from the same
problem...

(btw shingml is not username, it's a hostname: shingml.cs.huji.ac.il)

thks,
borik

P.S. I tried removing utmp and the problem shows up anyway.
