No. You can disable the moderation feature in your Moderation page.
However, we think that the main feature for a Social Wall is the ability to moderate content. What could be worse than having a bad tweet being displayed during your event on a giant screen in front of hundreds of people? That’s the story we’ve heard a lot.
We still recommend you use the manual moderation whenever it’s possible for you.
Note: Disabling the moderation can only be done when a Pro Package is active.
