Usenet newsgroups: news.admin.net-abuse.email. Just go to google and search that group for Rackspace.
They're slow to terminate spammers and/or their websites. Currently the more rabid anti-spam groups(The ones who will list all of the IP blocks from an ISP instead of just the IP addresses of the spammers) have listed most of Rackspace, and if you're there, and not being blocked, it's only a matter of time before it does happen



I think you may have misread my original post: I'm talking about Rackshack not Rackspace. A search on that newsgroup gives 2390 hits for Rackspace but only 191 for Rackshack and, reading through, the Rackshack mentions seem a lot more positive.
