I just called them to ask them to remove me from their listings which they said they would (apparently, I was also listed under "holiday gift guides" which explains all the random tech gadget holiday gift guide emails I've been getting...)
Just wanted to pass this info on to you all in case you're suffering from similar deluges of unwanted email from people promoting things. It may not be the only way people are finding you, but hopefully getting off their database will help cut down on the volume.
Here's their contact info:

It's worth a shot!
