That's not how it works. Doxing is also revealing the private info of someone when they've taken the necessary steps to distance their private life from their content-making profession.
It's not by chance that some anonimous channels were "doxed", and the doxing amounted to simply revealing the full legal name behind the anonymous account. That's also a form of doxing.
Did she ever publicly advertise her personal profiles? Did she do so intentionally and not by mistake? The post isn't doxing, then.
Did she actually take steps to make her private content invisible? Did people find it through "investigation" (really, stalking), or was it revealed in a hack? In that case, if you're posting content from her private social media, it's doxing. Even if it's just her social media handle, or her full name, and nothing else. It's very simple.
Were those pictures from her private social media? If they were, then it's doxing.
The rules state:
"In any shape or form" is pretty vague, and I think it's intentionally vague so as to include cases such as the one I raised.
Just for the sake of argument, Doggie Drool was doxed and she deleted everything. People still came here to share her private content, because "it's publicly available man" and "everybody knows her name now". Doesn't matter, it's still doxing. Those posts are routinely deleted, and I'm not entirely sure the posters weren't also banned as well.
In the context of the rules of the forum, any time a performer is taking steps to remain low-profile and distance themselves from their content creator past, then posting stuff from their social media is doxing. It's pretty clear from how the rule is enforced throughout the forum.
