There is no spam in my blog but when I created a backup (sql dump) the beginning is full of spam!!
There is miles of it interspersed in the posts!
There is more spam than actual text from the posts.
Its like all the spam I deleted using spam karma and bad behaviour are not gone, but just hidden in some way.
Under Manage / Comments instead of showing all the comments I have, there is only the first page of comments without any button to carry on back in time.
So comments could be on the old posts but I can't see them
