I haven't been banned or anything, but I did get filtered in English 1 chat yesterday, and I'm trying to figure out why.

I was trying to type out "I truthfully have no idea" but what I got was 'I **hfully have no idea'.  I thought I had hit the wrong key, so I tried to correct it with a "truthfully even" and got '**hfully even'

I finally realized I was being filtered on the word 'truthfully'.  Is there a reason for this that I am unaware of?  I have spent 2 days wracking my brain, trying to figure out what the filterbot thought I was typing that needed to be filtered, but I have been unable to come up with a single thing.  So my question -  is there something wrong with the word truthfully?  Or is there something I'm missing?
