I don’t think she cares whether it’s illegal or not. She thinks rules don’t apply to her for some reason.
Doxxing is a bit of a grey zone. Also in every country different, I'm not even on the same continent as her for example.
Basically if you just discovered things with publicly available information and just gathered them and posted them doxxing isnt illegal, it's their own fault, just like we are not doxxing her for taking screenshots from her account (although she has once accused somebody of this too, lol). It becomes illegal if you used illegal means. Most blantantly of course if you hack yourself into stuff. although you wouldnt even find identities then most likely, you need multiple leaks on multiple platforms to gather meaningful data. There is another grey zone: It's fairly easy for example to discover alt accounts on some social media platforms if you know how to scrap data properly. But that's also another grey zone, because for example Instagram doesnt allow scraping for such a purpose. I saw her people trying to find help from people who are into this stuff or some dodgy websites, so they at least considered that route lol.
The most efficient way is to pay attention to somebodys writing style and hints they occasionally accidentally drop. If you are lucky they are elsewhere too and perhaps you find more hints there, and so on, and so forth. That's completely legal and most likely to work. And I reckon some people here are elsewhere too (like in that facebook group). I used to moderate a pretty huge discord server until I got too busy with life a few years ago (yes, I do have one, Alice!) and I can say it's very easy to spot this stuff and in some cases you can find some pretty disturbing stuff about people, since most arent very careful (this is in context of catching alt accounts of banned users btw)
Obviously her being a celebrity both routes would be seen as doxxing even if it's not, but she has already said that she doesnt care anymore, so. It looks like her people tried the legal way and already got the wrong guy the other day
this kinda made sense 15 years ago, and I'm actually sure it applied to many of them, but why on earth would anyone be jealous of her
now? Truth to be told, I was mostly following them from the Forever era on (I was lurking in the mid 2000s because the drama with his fans was well known even beyond his fandom, I have actually barely watched anything with him in it, although I do like him, he seems pretty charismatic and I like his natural accent) and while I definitely thought that she is lucky I was very happy to see that my concerns about how they match up appeared to be very wrong at that point, since they appeared like a pretty cute family. I was actually pretty sad when I realized towards the end of last year that their marriage appeared to be breaking down. She will not believe this, but it is the truth.
