The notion of a "pledge to killfile" Andrew is thoroughly juvenile. I am probably as guilty (if that is the word) as anyone of negatively critiquing his conduct on public Debian lists; but I would be horrified to see him censored. Surely, even if every unkind thing I have seen written about him were true (and much of it is not), Debian is strong enough to handle this aspect of his involvement with equanimity. Nor as far as I know is there any indication that he has mishandled any responsibility as a DD or has been seen by anyone outside Debian to reflect poorly on the Project in any substantial way.
