Could you please explain again in more detail what this feature does? When should it be used or not used? If it is useful, why is it not active by default?
In normal protection we just add a random field that is not visible to spam bots.
However, in Level 2 if someone knows about that field and wants to submit then there is additional random code used in the field and needs to match it.
It is hardly needed untill default spam protection is working. Also, in level 2 spam many things might go wrong and so need to full test forms once it is activated.
Thank
