To anyone who received a private message that contained spam, I apologize. The person responsible has been banned and rest assured that even if you got an email notification of his message, there was no way for him to access your email address. Just don't respond to him.
The anti-spam measures I enacted a few months ago mostly defend against the automated kind, but occasionally a very determined human will get through. I do have a tool that will prevent new accounts from sending private messages until they've made a few legitimate posts, but I had turned it off at the requests of some new members who found it difficult to understand. I can turn it back on if necessary, what does everyone think?
Again, I'm sorry one got through the cracks.
