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 of disposable and temporary email domains. You can also create your own custom email domain block list.
Create a custom domain block list
From the top navigation bar, select [User profile] → Settings.
Under Advocate Settings, select Security.
Under Block Email Domains, enter the domain/s you want to block and select Add.
You can view or remove the domain under List of Blocked Domains.
Optionally, [Toggle on]Block temporary email addresses to block all users using a temporary email domain.
