We have been removing a number of spam comments from our site over the last few days. These comments are written to ressemble a real reply to a message, but contain links to external websites. Since we have spam filters to prevent computer generated spam, we believe the comments are being posted by an actual person.
If you see such comments, please email us the details at firstname.lastname@example.org so we can remove them and delete the accounts being used to post them. We appologize for the trouble.
