For the past 2 weeks at work we have been receiving Messenger Service messages everyday on servers and workstations advertising fat reduction or diplomas. They orginally started on servers at our hosting center outside of our firewall, then to servers on the inside of the firewall. A few weeks later we started getting them at our home office, and just today I received one on my non-connected to work, home computer. Has any one else been getting these, and if so how are they taking advantage of Messaging, what is their source, how do you make them stop etc etcetc?
