Black Bloc and others who favor "diversity of tactics" (essentially, some level of violence and property damage) have recently been going after livestreamers in Occupy (in particular in Occupy Oakland and OWS).
The first incident, a few weeks ago, involved OakFoSho in Oakland. He had streamed OOers throwing bottles at police during a Fuck the Police march (with no immediate police provocation) and called this out. He was subsequently called a "snitch", "traitor", etc.
Then, when OccupyFreedomLA was livestreaming the Occupy Oakland building takeover attempt, she criticized throwing of objects by BB, pissing some off. Later that day, in the middle of a march, her camera was snatched.
When OWS subsequently held a solidarity march for Oakland, people were asked to come dressed in black, A meeting was held prior to the march for a "diversity of tactics" framework. During the march a few people began throwing shit at police (a few bottles and bags of trash). Also, prior to the march, streamer Tim Pool had been threatened. During the march, someone (masked and dressed in black) tried to steal his cam, knocking him down and partially breaking the cam. People near Tim unmasked the assailant and posted his picture online. The OWS Solidarity Sunday march started chanting "Fuck the Police" very shortly after the attempt to snatch Tim Pool's cam - I've seen it said that the intent (of the attempt to get the cam) was to keep the "Fuck the Police" mass chant from being broadcast on livestream, though I've seen no meaningful verification of this claim.
The official OWS Twitter account then posted a tweet stating (falsely) "Tim Pool of @Timcast just tried to help #NYPD arrest an occupier", then deleted the tweet. OWS folks would not answer subsequent questions about this.

Last weekend, the official Occupy Oakland Twitter account asked that no-one post photos or video from #J28
At this point, multiple livestreamers have been called "snitches". There's been a strong push to not stream at all in Oakland, or to only film OPD misconduct, while avoiding filming protester violence or property destruction. And in OWS, it's also been argued that streamers should not film protester misconduct. A sample of the ongoing twitter conversation this week.
In the face of these attacks/criticism, many streamers are banding together in solidarity and are coming up with a bloc identifier of their own. The current favored option appears to be #SunshineBloc
My own thoughts - if Occupy loses its streamers, and especially streamers who are viewed as conveying events in a trustworthy fashion, it loses one of its most important assets.
