Do you have a comment policy for your blog? I never had a formal one and I hardly ever need to delete any comment. The few that I deleted were either obscene or blatant advertising.
But these days there is a spurt in comments that are vaguely on topic and then have links (sometimes more than 1) to a commercial website.
What do you do with such comments? I have deleted them till now but with a vague feeling. Thought I would write about it and then see how I feel.
I have till now managed without comment moderation but now I am seriously wondering.
