Hi Roberto,
Thank you for the feedback. I have cleaned up the spam messages in the forums. The original messages were posted through the Usenet newsgroups, and were replicated to the Developer Exchange discussion forums (Web interface). The system is set up so that all messages will replicate between the newsgroups and the Web forums. Because we provide multiple ways for the community to participate in the forums, these unsolicited messages can appear from time to time. If this becomes a continued problem in the future, we will investigate the best way to handle the situation.
Best Regards,
