Yes
Wait, let me actually read your post first

I would think that it doesn't cost these guys much more than time trying to scam people. There are lots of stupid people out there who will fall for crap like that. I mean, someone must have fallen for the Nigerian scam or why would they keep doing it?
Heck, this girl I went to high school with was taken by a scam. Her husband was going to be paid to put of these fliers and somehow receive money for people who called the number on them. However, he had to pay for the paper to make the fliers. He was told they cost Eleven Fifty. Of course he thought that meant $11.50, not $1150. The other guy taped the conversation and said its the other guys fault for not asking for clarification. In the end, the scam was overturned and that kid didn't have to pay that money, but god, who thinks they will actually make a lot of money putting up fliers...if something seems to good to be true, than it usually is.
I laughed as I read all about that in an article from my home town's local newspaper.
