I've been using Sendy for newsletters for several years. One of my lists, which uses Joe Workman's Post Office stack for signups, gets an inordinate amount of subscriber spam. I have almost 4,000 email addresses in my banned list. I've noticed that virtually all of these duplicate the same names in the Firstname and Lastname fields, e.g. AlbertepiniYU AlbertepiniYU or stefaniell60 stefaniell60. Does anyone know of a script that can compare these two fields and disable submission if they match?
