WYATT_JORDAN If I ignore a user will I still get email notifications of their posts?
Whether or not the platform has the ability to do that, if you can set a rule or filter on your email server that will do the trick.
If body of email contains [USERNAME], send the email to the cornfield (delete).
You won’t see any such notifications in your inbox when using your email client. It will most likely also work for unwanted PMs from [USERNAME].
