Spartan X, pest control, and other rants

We just had another Spartan Z person come by our house to not sell us solar by trying to sell us solar. We tried politely twice to tell him to leave and finally had to tell him to get off our property. Not to mention they skew facts trying to make it sound like they are a great bargain.

I am so tired of these companies coming by my house trying to schlep their wares. They use GIS to find out neighbors' names and lie that our neighbors are using their service.

I keep forgetting to ask if they have a permit and reporting them to the town.

And before you say not to answer the door, I was sitting on my front porch reading a book.

Has anyone had luck with a no soliciting sign or other means?
