I know many members here are doing blogging farm. Here is some tips IMO, so you can do better with SE. 1, different hostings, different IPs. no more than 3 domain per hosting. really different IPs. no XXX.XX.XX.1, XXX.XX.XX.2, XXX.XX.XX.3, ..., etc. 2, do not register all the domain names at one time. And different whois info for the domain names. 3, you need to select one niche per domain. 4, don't put sitewide links. 5, publish fresh, unique content. get some one to write it or use rewrite tool. becarefully when you rewrite articles, I think SE can check it. 6, do not publish the articles at the same time for all your websites. Maybe this can help you to do better. Also, plz share yours to reply this post. Thanks.
