Even if it's not filtered, if you change a word it's a bypass.
So that fb thing was a bypass.
It's because you're anticipating the filter, so you change it so it wouldn't star.
That's why I said you just need to always type out the word, so there is never any confusion.
Likë that hey? I think what she is trying to say is trying to adjust a word to make it a bypass. I will bet if it isn't a offensive word it won't be silenced.
