Hey there.. I posted my response to crypto.piotr, who memo'd me to ask my opinion. However... I got a prize for you...
What you want to do is stick a little red thumbtack to your exterior doorframe. The flat kind... Jehovah's Witnesses put them there to warn other Witnesses that the house is "unclean"... I found this out decades ago, because when they came my roommate casually explained that he was an athiest and I was a witch. The next day, we saw it up there. So just use a flat red thumbtack, and you won't be bothered. <3
