Criminalize the Internet Scammers?

I don't really know how we could go about criminalizing them but I do know that these people deserve some kind of punishment, not only are they stealing from people that are renting referrals or trying to increase their earnings by purchasing an upgrade, but they are also wasting people's time because there are a lot of sites that start up only to go down within a couple of weeks of being open. I've been a victim many times, joining lots of good looking sites that had great web design, I was figuring that if the admin was willing to spend that much time in the web layout, then they would probably be willing to put the time and effort into making a good site. It's also sites like Neobux and Onbux make it blatantly obvious that a site stands to GAIN WAY MORE from being LEGIT instead of being a scammer. Unfortunately a lot of people like their money quick with not a lot of work behind it, I just don't know how you could lack the respect of other people's time like that though.
