I think we have it under control now - we have disabled ~200
"suspicious" community accounts, restored a backup of the wiki from ~36h
ago and nuked all the session data from the community auth system and
the wiki to prevent users from reusing existing sessions.
That seems to stablized the situation for now but community auth account
creation is still disabled.
We are currently discussion further actions which will likely involve
adding additional verification for community auth signup and maybe for
posting to the wiki. We are also looking into restoring the handful of
"valid" changes to the wiki between the time of the backup and the time
we restored it.
