The 404.jodi.org.blaster allowed to write vowels into jodi's Message-Board von jodi. The message board seperates consonants and vowels from all messages and displays them on different pages so most sentences are unreadable.
404.jodi.org.blaster converted vowels into numeric HTML entities so jodi didn't recognize them as vowels and therefore didn't filter them. But after some weeks jodi found out about this cheap trick and startet filtering entities also.
The now obsolete --->404.jodi.org.blaster stays here as a sort of exibition piece.
