XF 1.2 Does not automatically setup some user

[NextHostingForum]

Howdy,
I have set registration to email activation. When some users register, their account is marked as pending, and then it asks me to activate them. Why is this?

Regards

P: Users are requiring administrator approval regardless of my "Enable Manual Approval" setting.
S: XenForo 1.2+ comes with a set of spam prevention features that will verify a registration against Stop Forum Spam, DNSBLs, and Project Honey Pot. Depending on your settings, it will either reject registrations or place them in manual approval. Check your spam settings here:
ACP -> Options -> Spam Management

OK lol, but those users are home users, I know them and they don't spam

You may still have your spam settings to strict, where some of them are becoming false positives. The system is automated, and isn't perfect, no system will be.
