It's soo hard. how can you establish rapport with the other commenters if all comments are moderated?
What theme? you mean same topic? yes I gree if that is what you mean, what I always wanted is to be approve in dofollow blog
blog commenting is a time consuming task and you need to be very careful when you are doing blog commenting. most mentors use words like Nice post’,’ I agree with you',' your blog helped me' like words these are total spamming and never get approved. so take time when you do blog commenting.
