Since I am using Karma plugin to sort out the SPAM comments I have no problems, but yesterday I received a complain that Karma is also bouncing the normal comments some time. My view on this is that I will not change anything, but I would advice to first of all watch the content of a comment you post to make sure it does not look like SPAM and second – if you visit my blog quite often and if you are interested on writing comments (I hope), then you\’d better register as a used here and this will help to make sure your comments are not filtered away.
