Dox Phonebooks is provided freely on Kiwi Farms. The most Josh does is make you sign in to view it for some threads. He is technically not making his money off selling dox but instead his podcast whinging about e-celebs. Even Kiwi Farms itself is not really a doxing website first and foremost but instead just Reddit with racial slurs. People donate because they believe without Josh, they would lose their place to worship Trump and say nigger.
California state law doesn't need to have a perpetrator to be a data broker, California state law explicitly states that if you dox people for malicious purposes then you will go to prison and/or pay some hefty fines.
California isn't alone in this, there are several other red and blue states that have made doxing a crime already (Nevada, Illinois, Arizona, Alabama, Texas, Florida, Utah, Kentucky, Delaware, Pennsylvania, Oregon, Colorado, Missouri, Washington state, Virginia, Oklahoma, New Jersey, and Connecticut all have laws that criminalize doxing). There's even bills currently pending in Congress that addresses doxing and offers legal protection from doxing for both public and private individuals. The American government itself also advises people on how to avoid getting doxed and what they should do if they find themselves getting doxed since the Biden years (which often involves contacting law enforcement to report a doxing). If you think Trump supports doxing, he doesn't. Even Trump condemned doxing in his memo that condemns the Charlie Kirk assassination where he criticizes the Left for doxing ICE agents and right-wingers.
As more states criminalize doxing, there will come a point where eventually Congress will address doxing too (much like how Congress finally criminalized revenge porn on a federal level after every other state made it a crime). We're now reaching a point where the law is catching up to Internet culture and criminalizing the really toxic aspects of Internet culture that is often associated with or is an accessory to a crime.
If Jersh still lives in Florida then he can get in a lot of trouble because doxing is illegal in that state. The same can be said with other websites that heavily engage in doxing where any of the AGs in these states I've listed can file criminal charges against them as well.
