As a former door to door guy that was pretty good at it, and now a homeowner in a development that gets them all the time, I laugh at myself because I simply don’t answer the door, which I hated when people did that when I was working. Most places have an iPad and keep track of sales, not interested, and not home etc. I had a company in my development the other week, and I just never answered the door, but over 3 days they knocked literally 7 times. So I could’ve saved my cats from sprinting to hide under the bed 6 times but I never interacted with anyone. Side note, if you have a video doorbell, they tend to knock instead of press it lol

Edit to add, FWIW, if I saw a no soliciting sign I skipped the house. Only time I knocked one is when I legitimately didn’t see it.
