Who are the current spam cancellers?
Chris Lewis and Robert Braver take care of most of the spam (John Milburn has retired from the spam-cancelling biz), while Richard Depew cleans up spews from horribly misconfigured news servers, large misplaced binaries, and the like. Somebody calling himself The Unknown News Administrator has been helping as well, and so have a few others. Michael Scheidell and others deal with problems (usually out-of-area postings) in various local hierarchies. Overall, Chris Lewis is considered to be the expert on spam cancelling, and one of the experts on Usenet in general. For a good overview of who’s doing what right now, hop over to news.admin.net-abuse.bulletins and check headers. It changes every few months.
