Kill off the Spammers Income
Perhaps I am being too simplistic but to me it seems fairly obvious that spammers aim is to get paid for spamming people to get them to go to various sites or advertise an item from a particular sails point.
Would it be too difficult therefore to put an immediate world wide block on a site that is paying spammers to push forward their site or goods (i.e., the one that you are taken to or the one that the link leads too. If the site is a legitimate one then they can appeal and be cleared after a suitable but very, very fast investigation.
If there is no money to be made by spamming then there is likely to be less interest in doing it.
Stop - because that is what needs to be done to spammers
