...Luckily, the majority of these bots are pretty dumb. You can thwart most of them by adding an invisible field to your form that should never contain a value when submitted. Such a field is called a honeypot. These spam bots will just fill all fields, including the honeypot. When a submission comes in with a filled honeypot field, this package will discard that request. On top of that this package also checks how long it took to submit the form. This is done using a timestamp in another invisible field. If the form was submitted in a ridiculously short time, the anti-spam will also be triggered.
