Sometimes blogger using BlogSpot as a subdomain, so their registration details, we can’t find out from who is database, also many bloggers using the namecheap domain service, so they are getting free who is privacy, and hide their name behind the blog. Also, some of the blogger does not include their name or profile URL in the sidebar and in below post content. So in this case, it is hard to find, out who owns this blog, actually many of pro blogger, using their own profile to create an anonymous blog and hiding their profile details on the blog post. Also, some of code master remove the rel=author attribute from blogger template, so you cannot find out the name in the source code as well.
Many of blogger, already know that blogger does not give you more control in our blog for example, in blogger sitemap, permalink structure, and ATOM feed :) so blogger can’t edit it. So, in this case we will use an atom feed to find out who is posting this stuff.
Know the author name behind blogspot/blogger post.
First off go to your victim feed URL.
www.example.blogspot.com/feeds/posts/default or www.example.com/feeds/posts/default
Replace example name to your victim blog address.
Now hit enter, and you will see some XML codes.
Now just press CTRL+F for finding codes, and enter
<author> in the search box, and hit enter
Now the author tag will be highlighted, and you will see these codes.

I think this is enough data to find out who owns that blog. Well, this trick is not working for private blogs. Also, you did not get proper details if someone creates a blog with fake names, but trust me guys, in most of the time they are using real names and hide their profile URL into the post. So in this case, this simple trick will surely work.
