I just found out that a lot of people are super uncomfortable with ao3 because of it specifically having a tag for non-con, which is completely valid, I get being uncomfortable with that, however I think people are missing the point of it.
Ao3 is designed to let authors have full creative freedom unlike other websites, but with that freedom, people are going to write stuff that's messed up, and having a way to quickly and easily filter out that kind of stuff avoids unnecessarily triggering people. I used to come across extremely triggering topics without warning often when I used wattpad frequently, so to be able to be warned and avoid that kind of stuff way more has actually helped me a lot more than you'd think with my mental health, which is what their tagging system is designed for.
Also, it isn't only used for fics that center around describing the actual acts, as it is also used when it is implied/referenced. For example, I read something once that was basically just bashing Mori (bsd) for all that the bastard has done, and part of that was referencing his pedophilic words and actions, which could be really triggering to certain people. That is what it's for, being able to find the fanfics that are enjoyable for you without causing unnecessary damage to your mental health.
Anyway, if anyone actually reads these, wattpad sucks, move to ao3. I will personally teach you how to navigate it, byeee
