She's referring to the event last year where she wouldn't stop tweeting about her partner's kids possibly being taken away because the partner's ex didn't like the idea of Laurelai being around his kids. She begged for money and then stopped tweeting about it as soon as she got paid. There's been no actual evidence of this shit happening, and she only brings it up again now as a way to say "see? even the transphobic gubberment doesn't believe the gossip online!"
Let's analyze this situation, if it actually happened that is. CPS visits Laurelai and Co., determines that there's no immediate danger (honestly I wouldn't expect Laurelai to be an immediate threat to anyone, more of an overtime threat), sees the house is clean enough and the kids are doing okay, decides its not worth their time to investigate further. CPS is notorious for only giving a shit if the danger is immediate i.e. they show up and Deadbeat Dad is drunk as a skunk in his underwear screaming at a gaggle of dirty children. CPS isn't going to give a shit if they show up and see nothing wrong, they're going to write it off as domestic nonsense where the absent party is trying to gain custody of the kids by throwing the other party under the bus.
So lets say they see a judge to determine whether or not the ex gets his kids back based entirely on the fact that he doesn't like Laurelai. CPS tells the judge that they scoped out the house, everything was in order, now all the ex has is online gossip. The judge is going to look at said online gossip and shake his fucking head. It doesn't matter if Laurelai is 100% guilty of what the gossip says, rumors and hearsay don't count as evidence. Any of Laurelai's victims would have to testify in person or give a sworn statement, a pastebin link aint gonna cut it.
The judge let's Laurelai's partner keep the kids based on the fact that there's really no reason not to. The ex didn't have enough to claim that the kids were in immediate danger, and pretty much his entire case is "i just don't like this new person my ex is seeing."
Therefore we can conclude that the ex had no case, and NOT that Laurelai is innocent of what the online gossip trolls have been accusing her of. The judge wasn't summoned to determine the legitimacy of the rumors, the judge was summoned to handle a domestic situation and determined the rumors couldn't count as evidence. Laurelai's trying to spin it as "the judge says its bullshit so I'm absolved of all sins", when that's not what happened at all.
