User Email Validation

[AJ]

Is there a way to edit the validation rules on the User email field? I assume that's one of the primary keys used for duplicate checking.

Use case:

We are creating Users who are multipliers who will never login to DT. But a unique email address is required for the user. Adding in a fake email address is a workaround but not a pretty one.

So the validation for a User comes from the fact that this is a WP user which requires an email address.

Instead of a fake email address, @Corsac suggested the better workaround of setting up a single Gmail address and then establishing Aliases in Gmail for each of the Multipliers.
