Not only is he a Youtube multi-millionaire, he has the kind of money that allows him to hire professional investigators who are former secret agents to track down Null and everyone he associates with. The kind of former Mossad people that Harvey Weinstein was working with to keep track of his accusers.
I remember warning Null extensively about all the porn on KiwiFarms when he was threatening to sue Epik over their tweets. What Null doesn't understand is that if Destiny doesn't make an concerted effort to remove the revenge porn from KF, then Destiny's accuser can go to court and claim that Destiny implicitly wants the revenge porn to stay up on KF and that Null is implicitly helping Destiny keep it up "because Destiny is widely known to be social with Null" (we know that this isn't the case, but this has been a persistent rumour about them).
In order to convince the judge that he too has been victimized by the leak and that he too does not want to have this material online (the "Destiny is himself a victim of revenge porn" part of what Frogninja wrote), Destiny has to be able to present evidence in court that he went out of his way to have any known instance of the leaked revenge porn removed from known locations online. He thus has no choice but to make legal threats against KF and other sites hosting the RP, so he can later convince the judge that he really really never wanted this stuff to leak online and is himself victimized by the leak.
Null should be able to understand the legal predicament that Destiny now finds himself in. If he still doesn't get it, he should ask Hardin to explain this to him. If Hardin isn't just about making money off of Null's litigiousness, he should be able to explain this to him in a way that will make him understand Destiny's position.
