They've also restricted registration to confirmed emails only, not sure if it's part of this move or not but previously you could put junk in and not confirm, prior to that you could skip adding an email entirely.

They've also restricted signing in to known-devices only, if you sign in on another computer you'll need to reset your password which will require adding an email if you haven't previously.

Or you can browse anonymously on the gimped interface at 'new' reddit.

I hope it backfires and they don't get the forgery-like growth this is supposed to present.
