I've developed a website in which the client allows registrations to emails with limited domains. But due to popularity of the site, it gets a lot of span sign-ups using disposable emails. I want to prevent such spam registrations and looking for a way to identify and restrict such users. Any ideas or extensions are welcomed.
To satisfy your requirements, check Magento 2 Restrict Fake Registration extension by us that allows restriction of sign-ups based on specific Email domains, first name, and last name character limits. Also, it has Google reCAPTCHA V3 that adds an additional security layer on registrations.
