Solution 2:  Implement “Honeypot” technique

A honeypot is a the small field within a registration field. CSS or JavaScript technologies enables this field invisible for an ordinary website users. However, this is not the case for the spambots who are likely to fill this field by default, therefore grab the attention of the website’s anti-spamming software.

When you add a honeypot into a registration form, we high recommend you not to change your external response in any way once its field is filled in. Moreover, showing the same type of message your actual visitor will normally see once the registration process is over. That way, you will prevent sending any signals that the fake registration has actually been considered as a spam activity.

But just as it is the case of CAPTCHAS, Honey Pots have their own drawbacks. These disadvantages are the amount of time it takes for the developers to apply an actual Honey Pot in the website’s programming code as well as the requirements for its continuous update to prevent spammers from enhancing their software to break through the anti-spam wall.

$customformKey = $require->getParam('form_key_hidden');
if ($customformKey == $objectManager->create('\Magento\Framework\Data\Form\FormKey')->getFormKey() . '259a8240fba23e82626efdc9eaa0c483') {
