I just discovered that there are four spamcop newsgroups on the Giganews server at news-europe.giganews.com:
spamcop.deputies
spamcop.geeks
spamcop.help
spamcop.social
spamcop.spam
The most recent posts are generally from or before 2010 though there seems to be at least one from me that's more recent than that (besides the one I just posted a little while ago).
Since the plug was indeed pulled on the Spamcop newsgroup server this weekend, die-hard newsgroupers might want to consider these.
