Periscope, Twitter's new live streaming video app, has barely been around for a week but is already rife with the type of abuse Twitter has battled for years.
The streams of female Periscope users have been flooded with rude and unwelcome comments, often sexual in nature.
"Yesterday morning my co-workers started a Periscope and in less than 30 seconds, along came the harassment," Sean Creeley at Embedly writes.
"There were only about 12 viewers of this stream, a quarter of users watching were there to do harm."
It's not an isolated problem, either, looking at various tweets:
Saw sexual harassment on Periscope yesterday. Poor young lady innocently showing her workplace and receiving a torrent of abuse. Not nice.

Looks like @periscopeco's community guidelines = Twitter's, but lacking the infrastructure to report harassmenthttps://t.co/q1RfzxZwBk

So, Periscope: for women, comments seem to be a constant stream of sexual suggestion. For fat men, just abuse about their weight …

Tried periscope a couple of times, you get weird random abuse and people you've never seen before. It's exhausting.
