I once set up a clan-forum and blacklisted the word "bicycle", just to test if the blacklist worked and what the error message the user would see. I forgot to remove it afterwards. Half a year later one of my fellow forum users asked me why they couldn't post anymore... After some inquiry, my response could be summarized as: "Ops...!"
This could be a similar situation - or the servers just hiccuped. ;)
I've written an email to Mr. Fulp about this, but it's around midnight in 'NG City' right now and it 'is' a Sunday, so do not expect any immediate responses/fixes.
Just as a bit of general advice: As a precaution, you should set the age rating of posts discussing "illegal text" to "T" or "M".
English isn't my first language, so there is 'a chance' that what you wrote means something else to "those who know".
