The danger in creating web 2.0's for back-linking lies in leaving a "foot-print" that could negatively affect your rankings later on. If I get a friend not from the internet to create a web 2.0 and they update it with articles that I send them, would this prove to be a successful high-quality back-link that's impossible to track back to me? I don't have much experience with cloaking and I'd rather stay away from it in general, but I think this would work just as well if not better in the long run, especially if the person uploading the web 2.0 is not involved in any online marketing activities. I believe what I described is essentially a private blog network without some of the authority and without the need to pay for hosting, domain, etc. I'm looking for someone's opinion that has done this before or someone that has experience with private blog networks or cloaking. What prevents people from creating a "web 2.0 group" that would essentially build each other's web 2.0's to eliminate footprints? How good is google at determining interrelated blogs from separate IP's. Another question: How many Web 2.0's should you create per account. I currently have two web 2.0's pointing to two different sites, but I want to create a 3rd that would link back to one of the same sites, is this safe?
