In my usual list of junk email from various spammers - that our company anti-spam system fails abysmally to detect - I got an email advertising the British Computer Society. As the BCS is an allegedly legitimate organisation I sent them and email complaining that they were being used by a spammer. Today they responded and admitted that New Wave were an official partner in some BCS promotion currently being run.
If you give money to spammer scum then you are as guilty as the spammer. As far as I'm concerned that makes the BCS a scum organisation. I felt really good telling they were scum for dealing with spammers, and even better as I have reported New Wave to the Information Commissioner's Office (not that it will do any good) for sending spam.
