You are responsible for your own consumption of media. The Archive of Our Own is more modular than many other websites – not only can you read a work's tags in order to decide whether that work is right for you, but you can even use a site skin that hides works with a given tag, so that you don't even see them in the first place. Assuming that the work's creator has properly tagged their work, they are not responsible for any bad feelings that may arise.

Fanfiction.net is a dying nightmarescape held together by duct tape and Faustian bargains, whose founder disappeared years ago when the Devil came to collect his due for reasons that are a mystery to us all. I will speak of it no further except to say that, if that site is dying, then Ficwad is undead. Furthermore, I know nothing of Wattpad or whatever else the kids are posting on today.
All of this is to say that my formatting advice is exclusively for posting on Archive of Our Own. If there are other guides for other websites, then I may add them to this list if you let me know of them.
