At first this appeared to be the answer to everything, although I gotta say this is appears to be a pretty complex, pretty heavy duty spam blocker.
However, it came to my attention that this plugin was preventing people from registering for my website (caught a legit email address and marked it as spam, forcing an approval request). But then, even after that, it prevented this user from being able to make a purchase on the checkout page of my website, causing JSON errors. I can't have a plugin breaking the checkout process for an ecommerce website. So this one goes on the shelf for now.
Now, granted yes, it could be that this might be caused by a 3rd party plugin conflict that I've not ID'd...but I don't have the time to hunt that down. Gonna have to keep looking.
I've had this plugin running for a week now and every day I'm emailed about more spam registrations. This is exactly what this plugin was supposed to stop, but somehow obvious spammers with mail.ru addresses are signing up.
While I can block those TLD's from being used (theoretically, we'll see if that actually works or not), I'm disappointed that such an obvious source of spam isn't being blocked as a default setting.
I don't know what's going on.
Today I spent 2 hours to figure why new user registration email not sending while admin notification is sent.
Mail server checked, external SMTP server used. All are same problem.
Once I disable this plugin, everything work like charm.
* WordPress version: 4.4
* I tried several times activate and deactivate this plugin. And quite confirmed it cause the problem I mentioned.
SPAM registrations seem to have increased after installing this plugin. I can't seem to find any reason why, so I'm looking for alternatives.
