Lost my site totally. It's not even in the top 1000 when it used to be first page. No backlinks other than a few ezinearticles, guest blog posts, and social signals. The ezinearticles and guest blog posts were written by me. And I think I did like 20 articles and guest posts in 1 year combined! The social signals are all natural, I didn't do or buy one. Funny thing is though that the name of the blog still ranks number 1, but anything else isn't even listed. Even if I search for a sentence of a post in quotes, all the people that copied and pasted my content are there, but my site isn't. It isn't deindexed because if I do a site: search, it's all still there. It's weird. Very weird. I'm thinking that it'll all resolve in a few days because there is nothing on webmaster tools and I haven't done any blackhat stuff. I saw a post of a guy that build a website, added content every week, never made a single backlink and he's in the same situation as me.
I send DMCA requests about the copied content, so will see what happens.
