Good Morning! Just got up.
I didn't install what I had originally discussed so you can forget about the issues I mentioned above. I did however install something else around 1 AM and monitored it until early this morning. It appears it is working great. I don't see a single registration from Spammer in that time and typically there would have been at least 10 at the pace they were going before the modification.
There is still a lot registered previously so over the next few days those posts might still appear but they should slowly dwindle to nothing.
