How to block registration from invalid emails? New User Registration Spam

[ankitpr89]

We are getting a lot of registrations done through invalid email addresses.

All the registrations are coming from different ip addresses. Of-course we can select and ban the users, but the question is HOW LONG?

One solution can be using captcha for registration, but unfortunately there is no plugin for this!
Do let me know how to stop this?

Temporary fix-

using this plugin: https://community.nodebb.org/topic/2187/question-and-answer-plugin-for-the-registration-form

nodebb-plugin-spam-be-gone does exactly what you require. Hooks into project honeypot to check IP against spam database. And has the option for a captcha. (Don't use the captcha, use the honeypot and the Q&A plugin that you're already using)

@a_5mith That's awesome!
