If so many people are saying "It feels bad to do this, but we have to do it to respect the precedent" why don't we just change the precedent?
I'd prefer that we don't instaban people for 3 months based on that sorta thing, really. I think one or two warnings, along with the post being edited, should be done before we start temp-banning people.
I don't want to echo Fandom's policies. Unless they've changed since the initial announcement, they instantly ban people for saying "a four-letter word starting with 'c' referring to a man whose wife is unfaithful" and "a four-letter word starting with 'c' being a more vulgar term for ******". Sure, we have to keep that content off to comply with them, but I don't want our punishments having the same ban lengths and (lack of) leniency theirs do.
I wasn't using the wiki the last time this issue came up, but I would've argued the same thing then.
Although, the precedent I suggest hinges on it being rather accidental. The report of N_Kardashev mentioned that they intentionally bypassed the filter, which I think should lead to a multi-month ban, as they went out of their way to break the rules. Did QuasiYuri do something similar? If so, I think a 3-month ban is fair for knowingly going out of their way to break the rules.
And as an aside....
Also people being banned for quoting a post containing the N-Word. Your instance in this is laughable at best.
That was a ban by Fandom, not us, I remember the community at the time thinking that that ban was unjustified. I'd really rather not use their judgement.
