For word cloud and text polls Vevox has a built-in profanity filter to automatically filter out some unsavory words. By default, this is enabled for all sessions. If you find it too restrictive or perhaps the content of your session requires the use of certain language you can always disable it.
To change the profanity filter settings:
Go to your session list.
Select the session you want to change.
Select 'Settings' in the navigation menu.
Select the 'Features' tab
Under 'Poll settings' toggle the profanity filter setting between 'on' or 'off'
Press 'Save'.
