I pinged nostr:npub18kzz4lkdtc5n729kvfunxuz287uvu9f64ywhjz43ra482t2y5sks0mx5sz a while back and we solved the problem that was causing me to not be able to connect to the relay.

As for purging dead users, there is a script by nostr:npub1cpstx8lzhwctunfe80rugz5qsj9ztw8surec9j6mf8phha68dj6qhm8j5e that I used a few months ago, but it was fairly aggressive and killed a bunch of live ones to that took me some time to find and resurrect.
