[Prophesy]

if it's possible,
not a terrible idea I'd say,

because it would be up to a user to enable it or not.

I personally wouldn't,
in fact,
whenever I incorporate words like that into my posts,
I actually type out "drek" and "frag" instead of the words that they get auto-replaced for.

I'm a big fan of the "cyberpunk" slang,
and even though there's not too much in-character and roleplaying in the forums,
it's still nice to see a few things like that,
makes me smile
