I've been on Periscope for 7 months and the amount of porn accounts is enormous. Currently, Periscope's policy as of 1/27/2016 is to report the inappropriate broadcast directly through the app. When watching a broadcast, scroll to the bottom of the info panel and tap the Report icon then tap to confirm. If you see a user posting abusive comments in a broadcast, please take a screenshot and email safety@periscope.tv. We are petitioning Periscope to make a way to report inappropriate images/accounts who have not broadcasted. Blocking them is not enough. They make several different accounts. We believe that if we can report the accounts who have not broadcasted, the more enjoyable Periscope will be. We want Periscope to be a safe platform for everyone.
