In the former there seems to be an implication that the server is generally not age restricted but the specific NSFW server IS age restricted.
You should have corrected your wording here. It's "
NSFW channel" and not "
NSFW server." The way it's worded made it sound like you were talking about two separate servers.
In Rule 6 of Leaflit's Discord server, it clearly implies that minors are allowed, and despite that, it's still treated as "
an adult server."

Now that is a bit strange. If the server should be treated like an adult server, then why are minors allowed entry in the first place?
Now, for the NSFW channel, there appears to be a form of gatekeeping. Users need to have the "
Adults" role in order to access the porn channel. I am unsure what exact method and process the moderators use to confirm someone requesting the role is actually an adult or not.
it would seem to me that the individual's presence is largely overblown. "That's how they act on there" is not enough for me to take a moral stance on whether or not it was ok for the minor to be present in the general chat.
Them being present in the general chat isn't an issue; instead, it's them being in the server in the first place. Especially when the rules clearly state the server is treated as an adult server. The people in the chats are talking about adult topics as well, even if they are not full posting images or videos of porn, the adult topics (like sexual stuff) being discussed is very inappropriate for minors to be engaging with. For example, a minor talking with adult strangers about femboys or porn is a major red flag.
This headache could all be avoided if they clearly stated minors aren't allowed in the server. Will this prevent every single potential minor from joining? No, of course not, but it will lessen the number of minors from joining. Since they would be banned if caught or leave of their own accord. And yes, of course minors can lie about their age, but in that context it can be argued the server isn't directly at fault for that deception. It's a hard issue to tackle, but it's better to attempt to tackle it instead of basically having a sign that says, "
Minors are welcome here! But we talk about adult topics, including sexual stuff. What could go wrong?!"
Having an NSFW porn channel and allowing minors in the server at the same time is
NEVER a good idea. Even if the NSFW channel requires some sort of verification, in this context it would be a role, which is indeed better than no role verification, but it's still a bad idea overall. Either ban minors and have an NSFW porn channel and allow the discussion of adult topics, or allow minors but don't have a porn channel and crack down on adult topics or segregate them.
Better yet, don't allow minors and don't have a porn channel at fucking all. It's that simple, Leaflit is the boss. If she says no NSFW channel, then there will be no NSFW channel. I don't see the point of such a channel. Shouldn't a Discord server for a VTuber be a place to discuss them and not to goon like a porn addict? Particularly since Leaflit is pandering to a right-wing and religious audience. The presence of a porn channel is so baffling.
As for the Christian thing, I don't know the specifics of her faith or whether or not is a grift, but just because you *are* a Christian and sometimes do Christian activates does not mean everything in their lives is explicitly Christian in nature. For example, brothels were very common in medieval, Catholic dominated Europe. People are just going to 'sin', like it or not. As far as I am aware Leaflit is not a 'Christian Vtuber' but a vtuber who happens to be Christian. She has secular fans, I imagine, who don't have a problem with NSFW content. The server, and I am willing to be proven wrong on this, is not explicitly Christian from what I have seen. So it makes sense to me that, despite her own belief, they would have a containment zone for 'sinful' content. In other words she is not enforcing her beliefs onto her community. Now, as a Christian you could say this is improper, but I would not necessarily call it hypocritical or grifty on its face.
She is commonly referred to as a Christian VTuber by multiple people. She has a Bible study channel for her Discord server. Leaflit collaborates a lot with a lot of other self-proclaimed Christian VTubers. She has a nun VTuber model. She has done multiple videos reacting to videos about Christian topics by the Christian YouTuber known as Redeemed Zoomer. Additionally, she reacted to propaganda videos such as those done by PaxTube (a /pol/tuber).




Even if she isn't officially considered a "
Christian Vtuber," in a de facto case she definitely has the reputation of being one. She definitely panders to a right-wing conservative and religious audience. Due to this, she should also cater to Christian standards. Especially since Leaflit is an influencer, it's very important for her to respectfully show Christianity in a good light.
In the Christian context, Leaflit choosing to have a pornographic channel in her Discord server is an utter mockery of the standards of Christianity. This is extremely hypocritical and sinful for her to allow such a channel. As I said before, she is the boss of her server; it's her choice to allow a porn channel. She can easily remove it but doesn't. This is sinful, porn is sinful, and allowing porn to spread in your server is sinful.
If Leaflit is known as a Christian VTuber, her having a porn channel for her Discord server reeks of hypocritical and sinful behavior. If someone considers themselves to be Christian. They should take it seriously by following the rules and standards put forth by the religion. This is especially very important for Christian influencers. A Christian influencer being sinful or a hypocrite harms and disrespects the religion.
