What needs to happen is the government needs to make it legal for individuals to track down and bash the heads in of the spammers. That'll put an end to it.
I dont even understand spamming now. THere is no use in it from a marketing standpoint as it will just be mixed in with thousands of other spam that a user will mass delete if they are not armed with a spam filter.
I have yet to meet a person who looks at their inbox and says "Oh, look, free 'V iCo Den', sweet! [click]".
Its a waste of time for anyone to take part in spamming.
