The worst problem with FF is honestly just the carebear nature of "you don't pay my sub" and people reporting you for a bully that allows so many of them to play like absolute shit. 'You pull you tank' players or 'please slow down were going too fast' ruin the game.
The players are absolutely mental though. The first screenshot is one of my all time favorites. Someone seeing an in game title and somehow thinking it is actually a FC for J6ers.
The best collection of people posting FF14 related things to laugh at is probably the /talesfromDF subreddit. From coomers to dogshit players to people complaining about people being tahhxic to the occasional actual fun interaction.
I didn't see anything about Dreadwyrm Academy in the initial post, maybe I just didn't read hard enough. It's a FC that basically acted like a cult to trap noobs into playing like shit forever. The second attached image is a collection of forum posts that were made after they had a fight with a member who wanted to do Savage Raids.
You can just search the name and find lots of people talking about them. They aren't the only FC like that though. Lots of them do similar things just to a less full on cult degree. So some people just get bad Rng and their 'new player for fun guild' they join traps them into being dogshit players forever.
They wouldn't let you use the marketboard. You had to ask a guild supply person to get you items. You weren't allowed to look at any online guides or Google where to start a quest.
I found an archive of their website about the "Three Pillars".
And a Google docs from around that time that has many reddit posts and chat logs if you feel like reading more.

If dreadwyrm was in the first post let me know so I can delete this.
