Periscope's live streams are generally very fast paced and that makes it difficult to moderate people who are trolling the stream or even making abusive comments. To combat this, the company has just launched a jury style comment moderation feature. So anytime a comment gets flagged as abusive or spam, the app will ask 5 random people in the stream if they feel it qualifies. If the majority agrees, it will result in a 1-minute ban for the offender. Repeat offenders will be muted for the duration of the stream.
