How can a new version make wpmu sites not delete your blogs? I bought the script before and done one blast on a privately scraped list of wpmu sites and got so high success rate in terms of registration and kept checking on validity of the accounts with a custom coded script every 2 days without making a single post and the blogs dropped quickly. Like being able to keep 50 live blogs after 2 weeks out of 1000 that were successful and that was without publishing. Imagine how can be the numbers after posting content with links to commercial sites. So I requested a refund. The script is pretty much well programmed and professional but the method itself is not anymore worth the costs.
