TWITTER DEBOOSTING

I have been making a regular Twitter post regarding the 'DEM Government in Exile Coup'. Today it was not posted. I changed the post to read 'Koup' not 'Coup' and the tweet posted. I am sure that this is old news. I believe that this is happening at the Client, in my case, TweetDeck. Does any CodeMonkey know where an individuals 'block list' might be stored? I have searched in all the obvious places (cookies) and have not found anything.

A central list of Deboosted words might also be helpful.
