Maybe I should tell everyone how to stop users with these types of email address.
1. Create a New Ban.
2. Name it whatever you wish but something that you'll know that it is for this purpose.
3. Scroll down to the email trigger and add an email as a wildcard such as "*@hotmail.com
". Please note that this will stop everyone from registering who tries to use that email in their registration!
4. Click Save.
5. Click "Add New Trigger" to add another email.
Remember, you must add each email as a separate trigger. There is supposed to be a way to add more than one on a line but it does not seem to work as expected. Also, when you save each one separately it is easier to find them say if you need to undo it and allow those emails to register again.
