it'd be great to have a script which extracts all of the rooms in a space, recursively through subspaces

#!/usr/bin/env bash

set -euo pipefail

hs='https://helsinki-systems.de'
accessToken='' # must match the HS!

recurseSpace() {
	local mxid="${1}"
	local pathSoFar="${2:-}"
	# Get some basic info
	local roomName="$(curl -fsLH 'Accept: application/json' -H "Authorization: Bearer ${accessToken}" "${hs}/_matrix/client/r0/rooms/${mxid}/state/m.room.name" | jq -r .name || :)"
	[ -z "${roomName}" ] && return # wat
	local roomType="$(curl -fsLH 'Accept: application/json' -H "Authorization: Bearer ${accessToken}" "${hs}/_matrix/client/r0/rooms/${mxid}/state/m.room.create" | jq -r .type)"

	if [ "${roomType}" = m.space ]; then
		# It's a space - fetch children and recurse them
		for child in $(curl -fsLHH 'Accept: application/json' -H "Authorization: Bearer ${accessToken}" "${hs}/_matrix/client/r0/rooms/${mxid}/state" | jq -r '.[] | select(.type == "m.space.child") | .state_key'); do
			recurseSpace "${child}" "${pathSoFar}/${roomName}"
		done
	else
		# It's not a space - print it
		echo "${mxid} - ${pathSoFar}/${roomName}"
	fi
}

recurseSpace "!MKvhXlSTLGJUXpYuWF%3Anixos.org"

this does however only work when you can see the room state and some rooms only show the state when you joined them which is why the list is incomplete for me:

I'd hope Graham is member of all of these. But I think in theory it should work when state is visible without being member

Mjolnir has protections to avoid a type of spam that has been common in other spaces, where someone joins and immediately posts graphic images. That protection was enabled, but is now turned off:

Available protections:
🔴 (disabled) FirstMessageIsImageProtection - If the first thing a user does after joining is to post an image or video, they'll be banned for spam. This does not publish the ban to any of your ban lists.
🟢 (enabled) BasicFloodingProtection - If a user posts more than 10 messages in 60s they'll be banned for spam. This does not publish the ban to any of your ban lists.
🔴 (disabled) WordList - If a user posts a monitored word a set amount of time after joining, they will be banned from that room. This will not publish the ban to a ban list.
🔴 (disabled) MessageIsVoiceProtection - If a user posts a voice message, that message will be redacted. No bans are issued.
🔴 (disabled) MessageIsMediaProtection - If a user posts an image or video, that message will be redacted. No bans are issued.
