The latest example of what I am seeing came this morning when I opened the Shopsmith Forum. Our newest member is Garryhof. If you click on the name this is what you will see.
Note the content of the Signature (at the very bottom). This is a link that I recommend you NOT click on. It takes you to what appears to be a company in the Ukraine that sells outdoor storage sheds. Maybe not hazardous but certainly not wanted (at least by me).
