Pr0n? Is that a new PC thing?
NO. That gets it by filters (mostly workplace imposed) that immediately block out the proper spelling of the word and make the topic impossible to discuss.
Not that new. It’s designed to get around dirty word filters.
It may also be an outgrowth of the onling slang of referring to photos of any physical object of mass interest (like watches, guns, collectibles etc.) as “porn”. That’s where I’ve seen it used most.
