Normally when somebody follows me I receprocate, except if its purely business site and something I don’t understand, which is very rare.
But sometimes I can’t access the site. I know its weird.
It leads to a page which says author has deleted the site. I got to know when I was in conversation with a fellow blogger on comments.
I couldn’t access his page. He has written about it in a post with the solution you can ask him the rest.
Go have have a look.
Here’s his post.
A suggestion from me when you are adding somebody leave a comment too so that they can tell you if they aren’t able to access your blog.
