As KG said, it's about time people got to grips with the Internet, and until they do, this stuff isn't going to stop. The lamers will find workarounds for everything, they'll find new ways to spam etc etc.
I think the sandbox idea is still the best, although even then, as so many people are ignorant to basic concepts, I should imagine this will cut down on about 2% of infections.
Unfortunately, this is such an expansive topic and could branch out into language barriers, the political correctness of that phrase, the dozens of other ways to possibly deal with it, different network's attitudes to spam, blah blah blah and so on, and these subjects are ones which people have such strong opinions about it's impossible to hold a logical debate..so I won't go there!
It's good however, that there are people like us who are at least trying to fight spam. Really great
