Over the last month we have been experiencing a significant rise in spam user registrations to the tune of 2-3K per day on my primary multisite install.
So, as you can imagine I have been in the process of implementing a number of measures to identify spammers to remove them or to block them from registering all together. Of course, it is a game of cat and mouse because with every change that I make it slows them down for a couple days and then they are back at it again.
So, the battle continues. However, as you can also imagine the new user registration emails have become a huge problem to my clients – getting dozens of them every day.
So, my question is does anyone know how or where to turn off the admin new user notification email without turning off the new user registration email?
I appreciate any insight you can offer.
