I'm not defending behavior like that. Personally I think someone is in pretty pathetic condition if they're posting that sort of thing in PF. Please do report it so SE can take it down. It's not game content so shouldn't be getting posted there.
I am attacking stances like yours that treat it like it's an extreme problem unique to this game and that SE has more responsibility for what children do than their parents have. All of that is false.
Discord server addresses are not explicit material. Looking at a Discord server address does not corrupt or exploit a child in any way. It's nothing more than a series of random letters and numbers (or are you also offended by use of the alphabet?).
A 13 year old with good parents or guardians isn't in any danger. Do you know why? It's because the parents or guardian are monitoring their child's use of Discord. They've taught the child not to join new servers without approval so their parents can help them stay safe from bad people. They've taught their child how to react appropriately to potentially dangerous situations they might encounter.
If somehow a child ends up joining that Discord server, do you know what my question would be? What the **** were their parents thinking when they allowed them to do it?
FFXIV is not a babysitter that is required to watch and be responsible for their child's every action in game let alone out of game. Parents need to stop acting like it is. If a parent hasn't taught their child internet safety then they shouldn't let their child use anything on the internet, including games.
Try taking your feeble moral outrage and do something useful with it like encourage parents to make better choices when it comes to their child's online activities. Encourage them to spend more time teaching their children how to identify and react to dangerous situations both online and off.
Also try talking to a real 13 year that wasn't raised in a sterile bubble. They know a lot more than you want to believe they do.
Maybe try playing the rest of the game instead of hanging out in Limsa or a housing ward with your friends that do nothing but talk about drugs and sex?
I do mostly ignore shout chat unless I'm in the middle of Hunts and we're relaying information. A good parent would have shout chat disabled if their young child is playing.
Why are you paying attention to shout chat?
I ignore the other section of Party Finder because if I'm looking for a party, I'm going to search under the appropriate category for the content I intend to do. A good parent will have taught their child not to use PF.
Why are you spending so much time going through the Other listings?
I'm not part of the RP community. A good parent would be monitoring their child to make certain the RP community they want to join is safe.
What part of the RP community you want to join is up to you though I wonder why you seem to want to focus on the ones engaging in explicit content.
Mods are against the ToS so that's a non-issue unless a parent is allowing their child to use mods. That's the parent's responsibility, not yours or mine or SE's.
Not certain where you're going that you think Crystal is nothing but degeneracy. It's not. I see worse on Aether and Primal (especially Aether) when I world visit than I will anywhere on Crystal with the exception of Balmung Ul'dah (and I try to avoid going there when I have reason to be on Balmung).
I don't use social media because it always has been and always will be a cesspool. SE has zero responsibility for what people do on social media.
Why do you spend so much time on social media exposing yourself to these things if they offend you?
Can you tell us where a dog is humping a human leg in the game content? Maybe it's in content I haven't done yet because I can't seem to think of any such situation. Though I wouldn't put it past you if it was an exaggeration in an attempt to demonize a game that you voluntarily continue to pay for and play.
The game comes with a warning about content and how player interactions are outside of the ratings review. It's up to parents to decide if their child should view such content and be part of player interactions. Try getting outraged at the parents who allow it if you're offended.
