content: And there's been zero word spread publicly about Twitter being used as a source for evidence to pursue an investigation? Surely that information would have surfaced in court at some point in the last several years. I'd think if feds were using Twitter, there'd have to be public filings related to their requests for data, and somebody would have found that significant enough to spout off to the media about it. Not to mention, if Twitter was also so concerned about the problem of political hate, white supremacy, "white guys with guns", etc. etc: why wouldn't they also use their platform as a service for the feds to monitor these "dangerous types"? I see where you were trying to go with this, but I also cannot see Twitter being a rich enough environment information-wise to serve as the basis for the kind of investigative work you are talking about. A forum like Voat? Sure, much more information rich as it concerns any individual poster. You can follow an account on a forum like this and find substantial comments, not just sporadic single-sentence blurbs on Twitter. If you're going to find anybody actually planning serious activity that might serve a warrant, they won't be doing it via Twitter. The purpose of Twitter is social engineering and shifting Overton windows. It's simple to astroturf and manipulate algos, and all anybody cares about are the meta stats like trending. So they can "push" the trends they want to. If the feds are going to get embedded in any kind of site for monitoring, it'll be a place like here. You can probably safely assume that any task force for child sex offenders has probably identified much more fringe communities online to monitor than fucking Twitter; their resources are also probably devoted to breaking up trafficking rings or porn producers/distributors, as opposed to nabbing the one-off dipshit making a couple inappropriate tweets. In fact, now that I've thought about this for a minute, the whole premise is ridiculous.
