I've been noticing recently that I get emails from blogger that there's a new comment on a post, but if the comment is one of those spam link to something stupid comments, it doesn't actually appear on the blog.
So, say someone writes a comment inviting people to visit a commercial site for plagiarized papers. I'll get an email of that comment (I get emails of all the comments), but the comment doesn't actually appear in the comments.
Are other people noticing that?
(I used to go in and delete spammy comments, but this is nice!)
