stop user registrations spam

[2cool]

Hi recently received many joomla user registrations.
If I disable user registration it also prevents virtuemart shoppers to register.
So I need to keep registration enabled because using virtuemart.
Is there a proper way to fix this?

1. Use Captcha
- Enable Captcha in Joomla Global Configuration
- Enable Captcha in VirtueMart Configuration (Shop) *
* Unlike what the label in VM configuration says, it is not limited to recaptcha.
You can use any captcha.

https://extensions.joomla.org/tags/captcha/

My recommendations:
I use Aimy Captcha-less Form Guard: https://extensions.joomla.org/extension/aimy-captcha-less-form-guard/
HashCash is back for J5, I used to use it on J3 sites and was also very good: https://extensions.joomla.org/extension/hashcash/

2. Enable Registration needs Product in Cart
In VirtueMart Configuration (Checkout) enable Registration needs Product in Cart.
This way only people who want to buy something can register.

Thank you iWim,

The second option works fine
Did not notice this option before.
