To verify these are real, can you have her check the UID of that Discord account so it can be matched to known instances of Dansburst's account? It's not too difficult, all it requires is changing one setting and then right-clicking on his messages.
I ask because we've already seen an attempt at pushing a faildox and this could easily be faked in multiple ways. New DMs dropping suggesting he's in Florida (or was in that timeframe) after the Rutgers photo raises some questions. Hope this doesn't come across accusatory, I just want to make sure this is done properly.
This is probably definitely the most appropriate course of action if this is legitimate. He's an actual child predator who is a danger to real victims and airing it out on Kiwi Farms could be damaging towards the prospects of seeing real consequences for his potentially criminal actions.
