He looked at it and promised to get back to me soon. The next day I got a phone call from their “VP of Indexing” (how many people in the world have that title?). We walked through my log file and he was pretty amazed by what I had found. It seems that some kind of DNS issue on their side caused them to use my domain (vertexdev.com) as some kind of default. I’m honored, of course. I asked him if this merited a T-Shirt and he thought it did, so I emailed my address to him.
As of this writing, they are still trying to figure out what is going on, and I am still getting the hits.
