Spam is such an annoyance, but nonetheless I have clicked on a few in my lifetime. Go figure!
I read an article in I think Newsweek, and I heard the government is trying to prosecute those who spam, and installing many regulatioins to hopefully control it.
But in my opinion, the only way spam will be controlled if there is a strong push for global regulation. If the USA and perhaps a few others try to do it themselves, then It's going to be a hard fight.
