Also, it's looking like Plex, when adding this email option, turned marketing emails back on for people who has turned them off:

I've seen this plenty of times, where I've turned off emails, and somehow they managed to get enabled again. Wish companies were required to keep records of these actions, and pay out fines for violations (actually pay them, not just sweep them under the rug w/ the FTC).
