# Block an Email Domain for Advocate

Your Advocate program supports flagging participants who have signed up with an email address from a suspicious domain.

We check referrals against a publicly-sourced and regularly updated [list](https://github.com/martenson/disposable-email-domains) of disposable and temporary email domains. You can also create your own custom email domain block list.
