Prevent any profanity or unwanted comments from being displayed in your Q&A by turning moderation on. If you're running Meetoo for the first time this might give you that extra peace of mind.
Review all comments or messages sent in to your session. Decide which ones you want to publish or hide from your participants view, making it a lot easier to track your session content.
The wordcloud in Meetoo has an automatic profanity filter which means that you avoid any bad language from being displayed on your wordcloud and prevent text responses from being shown to your audience.
