Website keeps getting hundred of fake users.
Registration form has reCaptcha but no effect.
By changing required fields in form to add First Name and Last Name required still fake users keep getting registered without adding First Name and Last Name.
The site has admin approval enabled. So fake users can't login and appear in the site.
The only way to stop the fake users that has been effective is to stop registering new users on the site. But that is not an option.
The fake accounts have a similar pattern.
