Reddit imposes new restrictions on Old Reddit - Engadget

So if I understand this right… people who left because they were mad, won’t have an old reddit to ever come back to if they ever decide to go back and haven’t logged in for awhile?

yes, around 6 months or you can become a moderator

So just make your own sub is enough?

It likely will only work for that sub. Betchya Redit will still block users from subs you don’t actively moderate
