In this article we cover:
Vevox has a built-in profanity filter that automatically filters out some unsavory words. This functionality is ON by default. (If it is too restrictive, it can be turned off again).
But should you wish to exclude other selective words or phrases that are not relevant to your session, you can manually hide them from word cloud polls or text polls whilst your poll is live and running.
This manual filter function is only available when you are running your polls from the dashboard.
Filtering words from Word Clouds
To manually filter out words, do the following:
From the dashboard, open your word cloud.
As the participant responses come in, you will see the words and their frequency count appear in the dashboard. Remember, participants can send in multiple responses of individual words or short phrases (up to 20 characters).
If you spot a word you would rather not appear in your results, select the hide icon (eye icon) next to the word or phrase. This will remove it from the voting results seen by the participants in Present view. You will notice a line through the selected word or phrase, and it will be greyed out in your dashboard results as well.
Should you wish to include the hidden words again then simply select the hide icon again, and they will re-appear in the results.
If the word you are filtering out has been sent in repeatedly, no need to worry about finding all the other instances of it. Vevox will automatically filter it and all other occurrences of it from appearing.
When you close the poll, you can continue to filter messages before you publish the results. However, once you have published the results to your participants, you will no longer be able to make changes to the responses.
All results submitted by the participants will appear in the data report. Even the ones that were manually filtered out.
Filtering words from text polls
Filtering words from text responses works by removing the entire participant's response.
In text polls, participants are expected to submit a complete sentence. Removing a single word from the sentence can alter its meaning. To avoid this, the entire response is filtered out when a word is flagged.
In the poll results, the full sentence will be hidden. To remove a specific phrase from your text poll, click the hide icon next to it.
When the profanity filter is turned ON, it automatically blocks certain pre-set words, which will be marked with the word ‘profanity’ next to the text. However, if participants use their own spelling or symbols to bypass the filter, you can manually hide these phrases by clicking the hide response icon.
