We are thinking about moving our main sales forms to the new Forms 2.0 but are worried that the number of form attacks we get might go up. We initally were using Marketo forms for our main forms and got a lot of spam and attackers because of it filling out the forms. How exactly does Marketo deal with cross site request forgery, cross site scripting attacks, and lastly just general spam? We would like to utilize Forms 2.0 but want to make sure we don't have anyone succesfully submit a form if they are trying to spam us or attack us. Any advice or help would be greatly appreciated.
