Now I am hoping that a human will review my response. It was actually a meaningful reply that was not spammy in the least. A human should be able to detect this. My first thought about being rejected by spam filter was maybe due to the fact that I have black hat in my e-mail address. Then I started thing some more. I am a Microsoft developer. In other words I am pro-Microsoft. Maybe the blog author has written a really smart spam filter that blocks out posts that are not pro-open source.
To quickly determine whether my e-mail address was the problem, I submitted the same response to the blog post using another email address. This time I made sure there was no reference to “black hat” in my e-mail or home page URL. I still got the same automated response from the blog. Who knows? Maybe all responses must get approved by the blog author. Well just for that I am not linking to his blog from this post.
