There are a few SOPA news stories out recently about the Stop Online Piracy Online act in the USA congress/senate.
“Inexplicably, and almost overnight, SOPA has morphed into a full-on assault against lawful U.S. Internet companies,” said Markham C. Erickson, executive director of NetCoalition, a group representing Web firms and public interest groups opposed to the law.
An acquantance of mine felt so strongly about SOPA that they were recommending "If I was someone who had "shopping carts" accessible on an internet site, I would make sure I had the best geolocation database I could, and if someone connected to my site from the USA I would tell them that we can't accept orders from the USA due to SOPA."
I'm presuming he felt that a few days of this and with a large volume of ecommerce sites, that it would make the US think twice about SOPA. I'm not sure that would help.
Another friend brought up the point that if you have a competitor in your business, they could claim you copied a paragraph of theirs and then start trying to shut down your site. Can you imagine?
