If I have a blog and as soon as I put fresh content out some spam sites trackback could Google give them credit for my content? I have a few site and the links are good but I want credit for the content. Thanks in advance for your response
I doubt the spam site will get the "unique" factor before yours, you can report this via Google Webmasters Central to be on the safe side.
I wouldn't mind as long as they link back to you. Make sure your feeds always only show excerpts, never full posts.
I was annoyed at first when it started happening with mine. However, most of them only have a short part of my post with a link back to my site. Most do not help with much but it did bring my authority up with Technorati. A few of them have also counted in my Google back links. Now I do not worry about it much. Many times they are banned from their host before they even get started.
I suggest you contact google and report to them google.com/contact/spamreport.html Not sure but in case google crawl that site more often then yours, then google will find your content first on that site, instead of yours
