I'm of two minds about this. Periscope, and indeed any other publicly social media, is an opt-in service. By using it you're saying "I want attention | I want to draw attention to myself | I want to draw attention to something". By publicly social media I mean publicly accessible Twitter accounts and similar, not private Facebook accounts.

People in the "public eye" invariably draw positive and negative attention. Does what amounts to narcissism need to be further coddled by essentially automatically filtering out negativity?

I understand that the tool could do with some work for private/family/friend only streaming or similar, but if you're going to put yourself out into the public forefront you should be able to take the good with the bad.

Cyberbullying is rampant, it's a big issue, but it's not a technology issue. The issue is with the people using it. For every kid that's experiencing cyberbullying there's another kid on the opposite end bullying them online. Let's stop trying to push responsibility onto the platform provider and instead focus on the people involved.
