Blog Comments: To Allow, Or Not Allow?

What’s your philosophy on allowing comments on your personal blog? A few days ago a guy offered a very complimentary comment on a Bible-teaching article on my blog. But, something he said made me think he was taking my point the wrong way. Tracking him down to his own blog, I learn that he styles himself a “sorcerer” who practices the occult. So, this was new–a sorcerer reading my blog and wanting to favorably weigh in on it.

Now, my blog comments are moderated, so I can choose whether to allow or disallow any given comment. His, I’m choosing not to allow, at least in part because anyone coming to my blog could accidentally stumble into him. Has anyone had similar experience?
