Im not a coder so I dont have an in-depth understanding. I would suggest you try editing your post a sentence at a time until you find a possible banned word and then rewrite the sentence to avoid it.
That is a work around, but not a fix– like using pantyhose for a fan belt. To the best of my knowledge, WordPress itself does not censor content in any way that would trigger on particular words. There is no reason you shouldn’t be able to use any word you want.
If you check that first of Pndsc’s links you will notice that most of the comments concern server level security software and settings– mostly mod_security, I believe. If this is the case it is not a WordPress problem and there is little that WordPress or anyone here can do, except provide advice for those who have root or sudo privileges on their servers, which tends to mean a VPS or better. Everyone else should check with their hosts. You may not be able to fix the problem even if you find it. Try that .htaccess trick mentioned in that thread. If that doesn’t work your host will need to get involved.
I have seen this in connection with certain plugins as well, so take a look at your plugins. Try disabling them, just to eliminate the possibility. It is conceivable that a theme could also censor posts, so switch to a default theme as well.
Please post URLs that demonstrate the problem.
