You likely are using words that don't pass the filter, which is a bit messed up right now. Here are some of the words that won't work, based on what I and others have found: http://www.funadvice.com/q/list_words. Add to that anything that says finger and you back to back.
Look for them in your status updates. If you're asking repeat questions...ones that have already been asked, that's where you'll find them.
