Rebuilding the Web-to-lead forms

Rebuilding the Web-to-lead forms

I've been having issue with web-to-lead forms for some time now. 

It appears bots are targeting the forms directly, now and then we will have a surge of junk leads come through, mostly from russian descent , if i check out analytics, we do not have the same surge in web traffic that the forms had. 

Some days the leads dont work at all, I have tested this by filling in the forms at random intervals over a month. half the time it does not work. 

I was advised to append a capthca to the webform but the captcha has always been disabled in the form builder. It's there, just not draggable so it cant be placed within the form. 

This issue is not isolated to one VCRM or CRM account, currently ive seen this on EVERY account ive setup or used with zoho
