the answer means nothing, yes, the supposed good action that triggered the question is the important thing. The only relevant part of the article is them claiming to have verified it, so it's Business Insider's word added to hers.
I'm not even going to touch the conspiracy theory madness, it's irrelevant, and the person in question has zero signs of being afflicted by it, her entire existence in the platform seem to have been focused on actually working against the issue.
Its also been pretty widely publicized twitter's issue with CP[0][1][2][3], and given how hastags are the way you find things in the platform it's natural that's the way they'd do it.
> Of course, she can't give out the hashtags and allow independent verification, yet somehow hordes of pedophiles already know these hashtags?
She is giving it out to journalists and apparently they are confirming it, it's not a tragedy that someone does not want to amplify possible child abuse, actually teaching even more pedophiles how to find it.
> How are they publishing those to each other, and if they have such a channel, why aren't they using that instead of Twitter?
Twitter is protected by its sheer scale, is huge making detection harder than dedicated sites, and is far far more stable, safe and accessible than some darknet website they'd have to run themselves on average.
> So who is she keeping the hashtags from then?
From the general public to not further humilliate the victims, from other pedophiles because its not some hivemind, the list goes on.
Not everything is about Trump, and you're falling for the same level of conspiracy if behind all this out of all this you see pizzagate Qanon.
