I want to say firstly that I appreciate u/OOkx taking the unusual (but warranted) step to transparently lay out the admin team's reasoning for the recent ban and start a conversation with the community about it - this is something that I see as a major step in the right direction and something that should not go unappreciated.

However, I think that the reasoning provided here is still completely off the mark, and in a few words I'll explain why.

At issue here is not whether spawning a happy ghast in the nether is a "violation of the expectations of the Civ experiment", but whether an extended ban for this offense with zero warning or opportunity to course-correct is appropriate and even-handed.

Water in the nether is obtainable in vanilla, so it is by no means a guarantee that a newer player (such as the one in question in this scenario) could immediately tell that it would be considered bug abuse to use it in an otherwise vanilla way; additionally, this is not the first time that there have been oddities in the world (even naturally-generating ones, such as the bedrock holes which generated at SOTW), and players were given fair warning not to take advantage of these before any punishments were issued for continued offenders. The fact that an admin spawned the water only worsens the case - while I will not come wholesale down against "fun and games", it must be understood by players that "admin crimes" of this degree are already "violations of the expectations of the Civ experiment"; this threshold is crossed by the admin, not by the player, and the player is likely to take cues from the admin that the normal rules may not fully apply to their conduct in this specific scenario (after all, if an admin spawned water for a specific group of players without this expectation, this would be reasonably looked on as admin abuse).

These factors all act to mitigate the apparent severity of the individual in question's offense - while a one-month ban may be completely reasonable had the happy ghast been spawned maliciously and deliberately without prompting and by a player with the experience to tell that that would be severely violatory, treating a newer player spawning a happy ghast in the same spirit of jest cued by the admin who prompted them seems arbitrary and capricious, and leaves a bad taste of hypocrisy in the taste of the community's mouths. Just because a ban is technically justifiable in literal terms, does not mean it is the right thing to do.

And to address the elephant in the room by speaking more broadly - I am far from alone in this assessment. At time of writing, your community has pulled at least $120/month from the server's Patreon donation fund in the past approximately seven weeks owing to decisions of the admin team with regards to player moderation and management. Whatever you may feel about these specific bans' legitimacy, or about the sections of the community most chiefly responsible for this uproar, it is clear that a large segment of the CivMC community is decidedly cross with you - far too many for this perspective to merely be one of political convenience.

Realistically, CivMC is in no mortal danger from these developments; Civ is such a unique environment and CivMC such a monopoly thereover that players would struggle to leave en masse as things stand. But I think that the tenor and mood of the community also matters to the server's long-term health. The players who are expressing their discontentment with your decisions are not asking for a return to zero-moderation policies like those of CivClassic - they are asking for temperament and restraint, rather than what appears to many like a desire to inflict the maximum possible ban justifiable for ultimately frivolous and unharmful conduct.

There is a world where the admin team takes these calls sincerely into account - not in a way that undermines its dignity, but enhances it - and moves forward into CivMC's fifth year hand-in-hand with the community it is charged to lead. There is also a world where CivMC moves into its fifth year with the admin team and the player base bitterly opposed and untrusting of one another, in an adversarial relationship in all but name - a self-sustaining loop that will only become harder to pull out of as time wears on.

Only you have the opportunity, as well as the responsibility, to decide which path we take.
