Hi,
There’s an special e-mail address where they respond pretty fast.
Whenever you have an issue with your Periscope app, account, etc. please e-mail the following address:
Safety@periscope.tv
They should respond pretty quick.
For everything else we do the best effort to help you here. We don’t get paid by Periscope (hopefully someday they look at us as useful and cooperative) so everything we do here is from heart for you guys.
Enjoy!
Luigi
