I have someone who regularly posts anonymous comments on my blog which I read and then delete. He (or she) of course is very upset that I don't allow their comments through onto the public area of my blog.
This post is directed to them. It's quite simple mate, have the balls to put your name on your postings and I'll let them through! Your real name of course! Not some pen name. Although something like "Bitter and Twisted" would probably fairly accurately describe most of your posts.
