I want to ask how you think parents magically know these warnings they see on many other games somehow take on a completely different meaning when it comes to 14 and how strict or observant you are expect parents to be of a 13-17 year old. I of course hope parents did teach their kids to be weary of anything online but just looking over the ratings I wouldn't fault a parent for not knowing a 14 has a massive issue with 18+ content, especially if they never played the game.
Let's take a look at the SE store listing shall we?

Hmm nothing about questionable online content but it is sold out so let's check the list of other recommended vendors they themselves linked.
Amazon: Rating pending on listing (Picture shows T with no descriptors of why)
Best Buy: Rating Pending on listing
Gamestop: Actually has the T rating, No mention of Online interaction or Users Interact
Greenman Gaming: Rating Pending on listing
Humble Bundle: Another T rating without online warnings!
Newegg: Only show T rating on picture on the box
Mogstation: Can't verify as I have every expansion
Not linked too but other versions of the game:
PS4 & PS5: Actually has Users Interact
Steam: Has Users Interact listed
Please explain to me how a parent is supposed to know based off of this at all? I suppose a good parent could watch their child play the game but unless you started in Limsa or made a character on Balmung I imagine after a few hours a parent would deem it fine and leave their kid be, especially if the kid is an older teenager.
