I want to use web 2.0 sites to get backlinks to money site. I'm not sure if I have use my own hosting or self hosting. Self hosting is free, it has good trust rank but there is very good chance to get banned. I'm beginner in BH techniques so it could be good start for learning. Own hosting costs a little money but you won't get banned especially at Wachahost (what I read here) and there are additional questions. Should I use shared, VPS or dedicated hosting? Shoud I use one domain with subdomains or buy multiple domains for each web 2.0 site?
