Yes, the submitted title ("You Don't Need a F@%!ing Blockchain") was edited from the original.

The original should certainly have been edited, but not because of the profanity (we're not Bowdlers here) but rather because of the clickbait. (That's the unless in "Please use the original title, unless it is misleading or linkbait." - https://news.ycombinator.com/newsguidelines.html)

In posts like this where the article begins by confessing to clickbait, the next sentence usually tells you what the real title should be. I've pinched that for the title above.

It's also misspelled.
