Remove email address from RSS feed

Is your feature request related to a problem? Please describe

My old host, Buzzsprout, had a cool trick. They would add your email address for authentication when you first listed your podcast in a directory, but after a week (after you've been added), they'd automatically remove it. It seems to really have helped with spammy requests to that published email address; I have another podcast on a different provider that doesn't do this, and my junkmail is significantly higher over there.

Describe the solution you'd like

Allow people to remove an email address, or add one and after a week, remove it.

Describe alternatives you've considered

Considered manually editing the RSS feed but hoo-boy, no thanks.
