Your end: A pointless system where autosurf programs/websites claim you can earn bank when you earn a few cents per website visited. Publisher's end: Crappy untargeted traffic that isn't going to buy anything.
From my personal experience I have my own defination of autosurf sites "Autosurf sites are scam sites which promises fool internet users to pay for surfing sites"
In the old days when you could trade banners it got you more impressions. These days the banner exchanger and ad tracking systems are smarter and don't count these hits so you are left with a bandwidth stealer that has no merit.
