I wrote a small script to open/close registrations on #Mastodon servers based on user count so that smaller servers can better cope with the current load.

You can find that script on @Codeberg :

https://codeberg.org/Windfluechter/check_mastodon.sh

You'll need to make some changes to the script (editing the limits) and most likely also want to use https://codeberg.org/Windfluechter/cleanup-mastodon-users.sh to automatically remove inactive accounts on your site to reduce the user count again
