'Bandit' Signs? (printers, shop, telephone, used)

[Steinish]

Have you ever bought anything or used a service from a business that advertises using 'bandit' signs? You know, those ugly, corrugated plastic signs that say "Fast Cash for Your House," "Affordable Dental," New Batteries," etc.
They're usually twenty feet up on a telephone pole, so I don't know how effective they really are ... I think they're a form of graffiti and I pull them down in my neighborhood.
What are your thoughts on these illegal signs?

I think the Coroplast companies and the Bandit sign printers have a nice little income from them.

I had a sign shop for 16years, and there was no money in those. Screenprinted in large quantities, one color ink they are only about a dollar apiece. I also find them to be annoying visual pollution, as well as illegal in most places. Likewise, I have never voted for someone because I saw their name on a sign, or they had more election signs than anyone else.
