Ghost users of the Internet are usually those who are engaged in illegal or immoral activities and as such should be removed as the parasites that they are. Organisations that promote this use are similarly irresponsible peddlers of filth and degradation and should also be shut down permanently.
Anonymous, free web surfing is a practice that - thankfully - is being stamped out. ISPs are now required to keep better records of clients. Illegal use of another person's wireless service is also being pursued so with any luck we are slowly getting our side of the Internet cleared up. Unfortunately, the USA and other countries are so far behind, they are specks in our rear-view mirrors and until these sites are shut down, everyone is at risk.
Sorry - but you have touched on a VERY raw nerve here. Nothing is free and everyone should act responsibly. There is no need for "free anonymous web surfing" unless you are doing something illegal and/or immoral.
SHARK!
