> it's still possible to extract audio from the video you are streaming, if you are perfectly still, streaming high resolution, lossless, 60FPS video of a single object very sensitive to vibrations in the air.

You would have to be trying extremely hard to get a periscope video which could have audio extracted, if it's possible at all with all the compression involved.

I didn't took that into account, thanks! Still much more is nowadays possible then people realise. And it scares me how little some users care about privacy issues when uploading photo's/video's.

Of course it doesn't means someone somewhere is going to try to harm you, but it's possible. It seems like the days where your username was anonymous and it was hard to track it back to you are over. Not sure if that's a good thing :(
