Locking this as quality of discussion not exactly high nor productive, and as discussing moderation actions in public is not allowed (as we can see how well this thread is already doing). From the thread author hoping for someone to die of an illness is just over the line.
To briefly comment the first post, the moderation team is a team, actions are more often than not discussed as a team and thus taken as a team. Furthermore the appeal system is in place where you can get the team lead and moderation team to review any bans if you feel you've been mistreated contrary to the community rules and policies in place.
In this particular case the ban history does not consist solely of one moderator's actions, and the perma ban resulted eventually from repeatable (and unchanged) bad behavior and other offenses where many other community members have been affected. If anything I'd say FAF moderation is quite lenient and gives multiple chances for users to improve upon their behavior, perma bans are the last resort.
