Just seen an interesting programme on telly where the BBC paid a website $3,000 and for that got control of 26,000 computers located in over 50 countries. A very sophisticated front end will give options on the use or misuse of all these privately owned machines from spamming so much to one website that many have paid cash to stop their businesses being closed down, to introducing clever malware like trojans, DDOS, key logging, password and encryption breaking etc. Scary they tested it on 2 tame sites and it only took minutes to obliterate that site. They finished by getting them to self destruct their malware progs on slave PCs !!
