Registration page

Good morning. In the past I used code snippet to redirect to a custom registration page. Now, with V2 I am assuming the example used with the plugin code snippet is not applicable any longer.

Therefore my question is, how can I turn off or use code snippet to perform the “similar” function?

I am getting spammers that are going to /wp-login.php or to /wp-admin. Is there a way for me to redirect them away from the default pages to custom pages?

Best regards,

Steve
