I've noticed recently that when I try and submit comments to various people's blogs, they disappear into oblivion. (My comments that is, not the people or their blogs.) What's more, there seems to be a random factor involved; sometimes I can leave a comment where it had been denied previously, sometimes it's vice versa.
Anyone else had this problem?

Update: I think I've got the problem sussed. Thanks to those who responded.
