The latter is correct. Patricia
was a spam bot which was mass-sending PMs to hundreds of members on this forum and a few others, advertising some site. The account has been banned and all the spam PMs it sent before being dealt with have been deleted.
It is not possible to revoke PM notification emails that have already been sent out though.
