So the other day one of our customers completed a form and used their good email address but then bad information otherwise - just a lazy form fill. The result, however, was that the customer record in SFDC was updated by Marketo to replace First and Last name with the new values entered for that email address - so in this case, they overwrote the first and last name to just = "x" which is how the customer completed the form. Sales now wants us to block marketo from being able to update customer contact records and so i'm trying to think through whether that makes sense to do or not...can probably do it at the SFDC level and just not allow the marketo sync user account to change primary field, i.e. first, last, etc.
Anyone have this problem and/or have an opinion on the benefits/risks to a solution here?
