But pedophile isn’t really taboo as a word, there is nothing sacrilegious about typing or saying it. PDF file is pronounced the same and means the same thing. The alternate version is just a rumored way to avoid being down ranked by a corporate algorithm.
Maybe I misunderstand your meaning.
People are afraid to say pedophile or it gets caught in a chat filter. I’m not a fan of calling it PDF files but if that’s what it takes to have this discussion, so be it.
