She gets you to mark her comments not spam. YOu’ll have to search for her email or username in your spam folder and mark it Not Spam and then Approve it. You will probably have to do this a few times, but Akismet does learn.
I have done that (approved her comments) – but what I don’t understand is that this person has been commenting my blog for years!!! But as of yesterday or the day before yesterday, she is suddenly considered as spam not only in my blog but in quite a few others – but not all.
