I do not run a dating company but how can dating be a SCAM? Or real estate a SCAM? I'm ok with you having an opinion but it also has to be somewhat factual.
Real estate signs are usually to sell a house, buy houses or help people with foreclosures. I'm sorry but I ran an extremely successful real estate company and bandit signs were an important part of my advertising campaign. If I put out a sign that said we buy houses cash I would pay 100% cash for that house. Would you be calling me a SCAMMER?
Even money making schemes, really if you are so against bandit signs you must hate infomercials!!! Either tv or the bandit sign the public can either look or not look.
Just think, if people didn't put up these signs then someone at code enformcment who takes the signs down, would be out of a job. So although not the best thing in the world it keeps jobs going :]
