I advise being careful with auto blogger plugin, people are using it for automatic spam distribution.
Even if you block a spam user, auto blogger will keep posting there spam, it is a security backdoor.
In my list of oxwall spam sites:

many had spam auto created from a blog
even if you block the user it doesn't stop the autoblogger entries from being processed, not sure if this has been fixe though. delete any spam users you find.
