Add temporary email domains to the default consumer email domain blocking list for form validation

Would love to see Marketo add temporary email domains (e.g., mailinator.com) to the consumer email domain blocking list for form validation. 

OR, alternatively, allow users to add more domains to block for their own instance. Currently you're not able to add to the existing consumer email domain blocking list, nor are you able to create an additional rule to block additional domains because the system does not allow two validation rules that reference the same field.

This can already be done by adding a new rule: https://experienceleague.adobe.com/docs/marketo/using/product-docs/administration/settings/global-fo...

No that's not correct. Two active rules cannot reference the same field.

This is really great idea!
In addition to the "two active rules on the same field" restriction, there's also a 2000-character limit per rule. This means that if you want to include a comprehensive list of temporary email domains (which is constantly growing as new ones are created daily), you'll be restricted by the character limit. Consequently, you'll have to select only some of the domains to include.
