This flyer was taped to my mother's front door today (click for a larger version):
Talk about deceptive. I can imagine that some residents (particularly the elderly) would get the impression that this was some sort of official city notice asking for participation in some type of official program. Pay attention to the "Public Notice" at the top, as well as the line "Your participation is appreciated." in the middle. It's also written in the third person, starting in the second paragraph with "An Independent Contractor of Address America will begin working on this street..." Not to mention, it's entitled "Operation House ID". How official sounding.
This is very deceptive, and I would not trust a company that markets this way further than I could throw its owner. Address America, Inc. sounds like a shady fly by night company, and I would recommend that you refuse to do business with them.
