edit: this is primarily addressing minor systems!! any system can be put in danger by doing this, but minors are especially at risk.
this point has probably been made 700 times already but can we please stop normalizing putting every crumb of alter information into your intros/descriptions. i'm really tired of seeing people list their trauma holders & let their littles roam free online & minors listing their sexual protectors publicly, PLEASE stop putting targets on you. yeah your intro or pk description might look pretty but someone is going to take advantage of that information eventually and/or publicly blast you.
^ this also applies to triggers btw, even positive ones. you may think you're preventing something, but if you tell the internet not to do something then they're just gonna do it more, especially if your triggers are more obscure/"weird".
i say this as someone who used to do all of this too, i thought it was proving a point and showing the fakeclaimers that i really AM traumatized!! yeah no it doesn't work like that. don't try to prove yourself to people who will never listen to you, protect yourself please.
