It's offensive (calling someone an idiot) in British English

yes, originally I was thinking 256. Unfortunately it's difficult to reach 256 without adding hate/vitrol/racist language

Ah, I see the problem. An awful lot of profanities are ethnic/racial/other minority slurs.

Perhaps some foreign-language and more obscure (dialectal?) English swear words could be used? With crowd-sourcing I'm sure we could reach 256.

as it was, I needed to make a call for swears and look up some different dictionaries to fill up this project

People are somewhat reluctant to share their profanity on GitHub

Make that call here and now on Hacker News, while this still has attention and is on the front page, and I'm sure you'll get contributions!

I suggest putting at the top-level of this comments section, so it gets more attention.

add filler words and turn them into sentences?

for now it is just profanity65 on the command line

Aw, that's a shame.

Is there no way to produce it in a format a normal GPG client could read?

Is there plans to implement this into a program (executable) or a website?
