Moderators are not just having their account banned, they are having their IP and email addresses scanned by the admin team to permaban them for life.

Proof? As this seems unlikely. Aren’t email addresses optional?
Proof would be good but honestly this seems pretty likely. Power users like mods are going to want the account recoverability so they're mostly going to be using authenticated accounts tied to real emails. And reddit sure isn't going to want them coming back to stir up their users. If I were reddit trying to double down this is absolutely a step I'd take.
It's private again, and tbh, if Reddit is replacing mods, r/Tumblr would be an odd place to start. Not putting much stock in this rumor.
