Tighten validation of honeypot field, perhaps?

[StephenPickles]

If a bot provides the value "0" in the honeypot field, the request will pass the anti-spam test. The code that tests this is in src/SpamProtection.php:
if (! empty($honeypotValue))
But empty("0") returns true in php.

I tested this by publishing the honeypot-views tag to my application's views, and changing the honeypotFormFields.blade.php to put "0" in the value attribute of the honeypot field.

I suggest tightening the validation a little because the present approach opens up a possible strategy for bots to increase their success rate.

Thanks for the package, which fills a gap; I've been seeing more and more spam user registrations in my app.
