Actually I got someone on an other forum to set up autoblogs for my 3 domains. I had a simple unique written-by-me content on one of those domains before and if I remember it well, when I searched for mydomain.com on Google, the results were the pages of the site itself. But when I search the domain now, this doesn't happen anymore. I've also checked these my 3 domains on this site:
http://www.iwebtool.com/google_banned? and yes, all of them appear to be banned and they are, as of the Google search results.
I really didn't know this could happen to my domains if I set up autoblogs on them. OK, so now I'm going to remove the autoblogs, create some unique content and try to ask for a re-inclusion. If Google doesn't allow it, then I might have problem selling my domains in future, right?
Thank you whitebark very much for your warning & explanation.
I also wonder if the same applies to parked domains? I know search engines don't like parked domains, but do they ban them as well?
