Recently we've seen a push by the government and even private industry to find a way to stop spam. Here's my idea:
All spam I get is advertisement for a product or service. Instead of wasting time trying a way to stop the spam from reaching the masses why don't they just severly penalize the company or product that's being advertised? It seems to me that they are going about it all wrong trying to find ways of filtering out the unwanted email. I think the better solution is to go after the companies that utilize it. Right there on the email is the contact information. If Joe Blow is trying to sell everyone a new mortgage rate then go after him. If he's sick of being fined a large amount for every infraction then he'll stop using spam email as a method of email.
Mr. Spam Sender will be out of business if companies don't want to be fined for using that type of service.
