It was very obvious which was which and you had a 50/50 chance. I can confirm this used to work and I always used a curse word plus the known word.

It was pretty big on 4chan at least at some point in the early 2010's. And the unknown word was always the hard one to read iirc.

This was extremely common on 4chan maybe 7 or so years back I can't remember the exact year and it worked for a very long time before anything was done about it and everyone knew to do it. Google asked for two words and presented them as two different fonts. The real word that needed transcribing was always identifiable and you could just write what you wanted as long as you got the second test word correct. Much fun was had.

Sounds like something 4chan would advocate.

More importantly, it's trivial to filter out everyone putting in the same swear.

4chan was doing it specifically with a six letter racial slur that's unrepeatable.

Since you're so afraid to use the word 'nigger' here's a book by a Harvard law professor you should probably read: https://en.wikipedia.org/wiki/Nigger:_The_Strange_Career_of_...

I guessed correctly: the author belongs to the one racial group for whom it's politically correct to use the word.

Better safe than sorry, there are enough people who think context doesn't matter.

So what's going to happen if you write "nigger" that you're so unwilling to write it? It's not like you'd be calling someone a nigger, you'd be using it in a clearly informative manner,

My understanding is that some folks have gotten in trouble anyway. Good luck to you!

I don't care to find out.

not really. it started with the word "penis" for the original "campaign" but since a single word was obviously ineffective the meme improved.
