It never occurred to me that moderating comments avoided third parties receiving spam. It never occurred to me because I don’t believe that is what usually happens. However, this was the reason I was given for a moderation being set on a blog site. It raised a number of thoughts and questions.
There are bloggers who, for clear reasons, do moderate comments sent to them. Perhaps they have had direct offensive experiences. It is unfortunate that the blogger still has to filter out unsavoury material to maintain a blog as s/he wants it to be.
The group blogs also have moderators. Moderating in a group blog, is I think, rather different to choosing to set up moderation on a personal blog, though the outcome may be the same.
Sometimes, people write and close off responses to a particular post. We can all respect this, and as far as I have seen, we do.
Setting a filtering mode means you as the blogger can maintain the superior stance in any exchange of ideas, especially if only selected responses are shown. It doesn’t offer contributors a total picture of the differing points of view or, of the the overall discussion that takes place It mirrors what the unbalanced, biased media do.
