Extend Global Forms Validation Rules To Allow Unlimited Or At Least a Custom Limit

[syaneva]

We have identified around 8K+ bogus domains which we would like to exclude from our Marketo Forms Submissions. However, there is a 2000 max limit of custom domains which can be added in the Global Forms Validation Rule and we are not able to restrict all bogus domains we have identified for exclusion.

It would be ideal to have the limit of 2K max domains removed so each Marketo customer can add their own list in the Global Forms Validation Rule. Or if not possible, another option would be to provide the list of bogus domains in a .csv file to the Support team and they to support us with updating the default list which is provided by Marketo in the Global Forms Validation Rule.

Small add-on to this idea, as it would make sense to put on the 2026 Product Roadmap as a Treasure Chest feature: implement disposable as a toggleable option and have it filter records coming into the database and/or form submissions.
