Hi there and welcome to the Community, @La_Vie_Nature 
Many thanks for sharing your thoughts with us!
I completely get your disappointment and I am really sorry that the widget doesn’t have built-in spam protection options now.
You’ve mentioned that you’ve used reCAPTCHA, but it’s not supported in our app. Could you please specify what’s been used as a reCAPTCHA in your case?
Anyway, we have a CAPTCHA request in the Wishlist and you can upvote it here - Add captcha.
The good news is that we have a custom solution to prevent spam in the widget. Feel free to try it out
