During Facebook CEO Mark Zuckerberg‘s live-streamed speech on the dangers of censorship on Facebook, viewers saw a flood of almost entirely positive comments and emojis.

There were also negative responses, but most were not visible during the talk because of how the algorithms behind a live stream with tens of thousands of viewers work.

Facebook does not show all the comments in real time on popular live broadcasts because the volume is too high, said Tucker Bounds, a Facebook spokesperson. To choose what does appear, Facebook relies on a number of “ranking signals” to filter out those that are low-quality.

The signals include how much people interact with comments and if something is “engagement-bait”, according to a Facebook post from earlier this year. The system applies to all comments on public pages and posts with large followings.

Nothing was unique to Zuckerberg’s speech, Mr Bounds said.

Some people on Twitter noticed the comments streaming alongside Mr Zuckerberg’s talk were almost universally positive.

Viewers left more than 45,000 thoughts on the live stream at the time it ended, and the ones shown during the speech were primarily thanking Mr Zuckerberg and Facebook.

However, more negative comments were visible after the talk ended and the option to sort comments by most recent appeared.

Sad or angry emoji faces were also rarely shown on the CEO’s public stream, where animated reactions floated by in real time. Thumbs, hearts and laughs appeared.

The reason, says Mr Bounds, is that the system shows emoji based on proportion instead of one-for-one – a necessity for a highly watched stream on which more than 80,000 emoji reactions were shared.

Angry faces were clicked around 900 times during the broadcast, while the thumbs-up was used 77,000 times, according to statistics on the video feed.

During the 35-minute talk at Georgetown University, Mr Zuckerberg passionately defended the platform’s approach to free speech, saying ”I believe we must continue to stand for free expression” and that the cost of not allowing free speech, in all its messiness, is “too great”.

It is not Facebook’s first run-in with confusing moderation. The company has been under fire most recently for its policy allowing political ads that are misleading or contain lies.

It has also been criticised for helping spread disinformation ahead of elections and allowing hate speech.

Facebook has tested out different fixes for its problems, such using artificial intelligence to identify hate speech, adding fact checks to controversial posts, and minimising how many people see something that has been identified as untrue.

The commenting system is an example of how Facebook uses technology to decrease how many eyeballs see problematic posts, while the company sticks to its stated free-speech policy.

Content is not necessarily removed from the site unless it is identified as something that violated Facebook policies, such a threat of violence or hate speech. In this case, the comments that the automated system identified as being lower quality were simply less visible.

As for the comments that did surface during the stream, they were mostly grateful for the site and its CEO. “Thank you for Facebook, it is a powerful applications bringing friends and families together,” said Eunice Maku Ayiku-Nartey from Ghana.

“Thanks for creating such an amazing platform that makes it easier and convenient for us to [reach] out to our loved ones and friends without stress,” said Mary Gabby.
