The press release (http://www.sophos.com/pressoffice/news/articles/2008/03/pitcairn.html) is titled "Pitcairn Islands relays most spam per person, reveals Sophos" and includes the following statement...
"Just because your PC is located on a remote island in the South Pacific doesn't mean it's not contributing to the global spam problem."
If Sophos don't realise that these servers are nothing to do with the people of Pitcairn, then they are "technically ill-qualified" to comment on IT matters. If they do know that, then they are just slandering a small community in order to draw attention to themselves, and "morally ill-suited" to comment on anything. Take your pick.
