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 meetings. If you find it too restrictive or perhaps the content of your meeting requires the use of certain language you can always disable it.
To change the profanity filter settings:
Go to your meetings list.
On the meeting you want to change press the 'more options' (or three dots) icon.
Select the 'Features' tab
Under 'Poll settings' toggle the profanity filter setting between 'on' or 'off'
