I created about 12 Web 2.0 properties on 14th of March, added a post with a link back to my site, then blasted them according to a schedule. I completed their profiles as much as they asked, verified email and used an email at my website. I also changed the default theme/design and made it look nice. I just checked now and realized that my accounts at wikidot, and onsugar were deleted. How do you guys prevent this from happening?? should I feed my web 2.0 properties with articles that don't link to my website?
