Registrations are manual approval for a while

We have been under troll attack for a while now. For this reason, I am giving up on the open registration policy for a while.

I will also add a rule for extremist users. Even though I care about freedom, I don't like moderation duties very much :) These users must find a new instance that matches their identity.

We’re also looking for an admin who can volunteer to moderate. They should be someone who has spent a few months in our instance, has a clean moderation history, and is active. In short, they must be someone we can trust. @[email protected] and I are busy these days :)
