If a large number of users adopt a new slang term on the explicit grounds that it is a 1-to-1 synonym for "dox", that would have zero impact on the ability of hit pieces to accuse this site of doxing. Any article would simply need to note "'xxx' is Kiwi Farms' euphemism for 'doxing'" in a parenthetical or, if they are feeling ambitious, could simply replace the term with "dox" within brackets. As the term is not a real word, most readers would take the article at its word. A minority would Google the term to confirm what it means. As Kiwi Farms is essentially unlisted from Google, the first result would confirm the term is indeed a Kiwi Farms dog whistle for doxing and criminal harassment, and that anybody using the slang term is probably a terrorist.
