Gossip client has settings for "Require approval before connecting to relay" and "Require approval before AUTHing to relay", and you can approve just once, or you can save that approval for every time. You can also go to the relay page and change your mind.

Love these settings - well thought out. I’d like to see more of this.
Gossip has the best relay management for Twitter style feeds. Running it, you can prove to yourself that it can work.
