Will write a proper post later. But right now....so sorry for that spam that keeps appearing on my blog - as quickly as I am deleting them they keep appearing!!
From now on all posts older than a few days will be moderated. If the problem persists when I may have to move to all comments being moderated and I will ruthlessly chuck out anything that looks like spam.
So, Ed, whoever you are - cease and desist!!!
Incidentally, does anyone know how to block particular commentors or stop this kind of thing from happening?
